Splitting Methods
Equal Page Count
Split PDF document into files containing equal number of pages per file.
Split By Page Ranges
Split a PDF document based on manually defined page ranges with a multitude of available options such as odd/even pages, reverse order, page ranges from individual bookmarks and etc. This method provides a lot of flexibility and allows for the mixing of different page extraction methods, from manually defined page ranges to page extraction by text and content.
Split By Bookmarks
Split a PDF document based on specified level of bookmark hierarchy, every bookmark section is extracted in a separate document and automatically named using the bookmark title. In few seconds you get a set of documents that logically split the original file, with every document even having a readable name! AutoSplit™ plug-in can automatically create folders on a disk to mirror hierarchical structure of bookmark trees. All output documents are instantly organized saving you many hours of work. HTML index files can be automatically generated to provide easy file navigation.
Split At Pages With Matching Text
Split large PDF documents, containing groups of pages of variable lengths into separate files. Reports, invoices, billing statements can be efficiently processed with this splitting method. The input document is first searched for pages that contain a user specified text pattern. The document is then split into multiple files at the locations of those pages. Pages that contain matching text become first pages in the corresponding output documents. A common approach is to match text that is present on the first page of every group of related pages (such as invoice or report). Text search can be limited to a specific area on the page to eliminate unwanted text matches. This operation can either combine multiple output documents into a single file based on the common search pattern or output separate documents. The first option is useful when it is necessary to find and combine all pages that belong to the same account or person into a single document. This processing method is available in AutoSplit Pro™ package only.
Split At Pages Where Text Changes
Split PDF files at pages where text within a user-specified area on the page changes. Example: input PDF document of 11 pages has 3 separate invoices, the goal is to split each invoice into a separate file. Each invoice may have more than one page and a number of pages per invoice is not known in advance. First page (or every page) of each invoice contains an invoice number in the upper-right corner and this number is always located within the same area. This document can be easily split using "Pages where text changes" mode by selecting a location where the invoice number is located. The plug-in will search all pages of the document and split at pages where the invoice number changes. All pages from the "change" page and up to (but not including) the next detected invoice number will be included into a separate output file. This operation can either combine multiple output documents into a single file based on the common search pattern or output separate documents. The first option is useful when it is necessary to find and combine all pages that belong to the same account or person into a single document. This processing method is available in AutoSplit Pro™ package only.
Split At Pages Where Text Pattern Changes
Split PDF files at pages where a specific text pattern is changing. The plug-in searches all pages of the document for occurence of the user-specified text pattern (regular expression syntax is used to define a pattern). If a page is found with a matching text that is different from a previous match, then a document is split at this page. All pages from the detected page and up to (but not including) the next detected page will be included in a separate output file. This operation can either combine multiple output documents into a single file based on the common search pattern or output separate documents. The first option is useful when it is necessary to find and combine all pages that belong to the same account or person into a single document. This processing method is available in AutoSplit Pro™ package only.
Split By Blank Pages
Split PDF document into multiple files at blank pages that serve as document separators. Every range of pages between blanks will be saved into a separate PDF document. Blank pages will not be included in the output documents. Pages should contain no PDF elements in order to be recognized as blank ones. You can even split at blank pages that are scanned images (in this case page should contain only a single image of the scanned blank page). This powerful feature allows processing of batches of scanned fax pages. User can adjust sensitivity of the algorithm to process images that contain some amount of noise. This processing method is available in AutoSplit Pro™ package only.
Split By Stamp Annotations
Use this splitting method when it is necessary to separate pages from a PDF document into several different documents based on stamp annotations. The stamp annotation on a PDF is intended to be viewed just like an ink stamp on a paper document. Typically, a user is reviewing documents and adds stamp annotations to a first page of each sub-document (invoice, loan application, application form and etc.). For example, a document contains multiple loan applications and reviewer stamps individual applications with either “Approved”, “Rejected” or “For Review” stamps. By using this splitting method it is possible to create 3 different output documents grouping sub-documents based on a stamp. First document will contain all documents stamped with “Approved”, second with “Rejected” and a third one with “For Review” stamp.
Split At Pages Where Page Size or Orientation Changes
Split PDF document into multiple files at pages where page size or orientation changes above the user-specified threshold. This operation can either combine multiple output documents into single file based on the common page size or output separate documents for each continuous page range.
Extract Pages by Text Search
Automatically find and extract pages that match keywords or text patterns. Use simple text queries or powerful regular expressions. Extract single pages, page sets or page ranges that match your search criteria. This method is used when it is necessary to extract pages that share common characteristics and group them into a single file (for example, reports submitted by a specific person).The pages can be located anywhere in the input document and do not have to be in a continuous page range. This approach is preferable when the number of output documents (and text patterns) is known in advance and the pages need to be grouped based on a search criteria. The plug-in searches page text and text content of all annotation types, including annotations created with "Typewriter" or "Text Box" tools.
Split by Content
Automatically find and extract pages that contain specific PDF elements such as forms, images, links, comments, notes, rubber stamps, highlighting, JavaScript code, transparency effects, page rotation and many others. 18 different options are available.
Batch Processing Support
Create your own batch sequences for processing multiple documents at once. Supports Acrobat's standard batch processing framework. Batch processing support is available in AutoSplit Pro™ package only. Three batch commands are installed by the plug-in: "Split Document", "Merge Documents" and "Extract Embedded Files". Here is a visual step-by-step explanation on how to split PDF documents using Adobe Acrobat's Action Wizard.
Launch From Command Line
It is also possible to launch AutoSplit batch sequence from outside of Adobe® Acrobat®. AutoSplit can be started from a command line or a operating system batch file (more details).  This option is available in AutoSplit Pro™ package only. You can also use AutoBatch plug-in if you need more flexibility in executing Acrobat batch sequences from a command prompt.
Page Ranges From Bookmarks
Interactively define page ranges from any bookmark in the document.
Save Settings for Future Reuse
Save and reuse complex document splitting profiles. All application options can be saved into a file for future use.
Automatically generated HTML index file
AutoSplit™ plug-in automatically generates an HTML index file that lists all output documents and links to their locations on a disk. A document index is useful when splitting a large PDF file into smaller ones for faster web access. Put this index file on your web site along with PDF documents to provide fast and convenient access to large document collections.
Security Options
Password Protecting Output PDF documents
All documents can be optionally automatically secured with a password. Users will be prompted to enter a password when trying to open such documents.
Restrict Document Access
Security options for allowing editing, printing, copying to clipboard and editing text notes can be applied to output documents. You can control the level of access to the document by restricting certain operations that can be performed on the files. Document editing and printing permissions can also be password protected.
Output Options
Transfer bookmarks
Transfer bookmarks to output PDF documents. Every output document can receive an exact copy of the bookmark tree from the original document. The biggest surprise is that every bookmark still points to the right location!
Update links
Update links in output PDF documents to point to correct locations. After splitting a document many links from source document can end up in different documents. Software can automatically adjust update links, so they continue to point to correct location in the same or a different document. The plug-in adjusts page navigation actions for link annotations and form elements such as buttons.
Insert cover pages
Automatically insert/append cover pages into all output documents from other document(s). This option is useful when it is necessary to add a standard cover letter at the beginning of every output document or append some common pages at the end of each document.  
Fast network access
Linearize output PDF documents for fast Web or network access. This can greatly improve document loading time if you plan to share documents on the Web or local network.
Add Watermarks
Add transparent watermarks to every output page (available only for "Split by Manual Page Ranges" method). Transparency level can be adjusted from 0 to 100%.
Open output documents
Optionally automatically open all output files in Adobe Acrobat for inspection.
Email Output Documents
Automatically distribute output documents to designated email recipients using custom email options.  Each output document can be optionally emailed as a file attachment to a number of email recipients (including "CC" and "BCC" options). Documents are emailed via a default MAPI-enabled email application that is installed on the user's computer. All popular email clients such as MS Outlook or Thunderbird do provide this functionality. The ability to email files is only available in a "page ranges" splitting mode when a number and content of output documents is known in advance.
Overwrite Document Properties
The plug-in provides functionality to specify custom values for the following document properties: "Title", "Author", "Subject", and "Keywords". If no custom values are specified, then the software will transfer these properties from the input document. The ability to specify custom properties is only available in a "page ranges" splitting mode when a number and content of output documents is known in advance.
Automated Document Naming
Flexible Output File Naming
AutoSplit creates unique names for output documents based on the following scheme: Name Prefix + Base File Name + Automatic Suffix. The filename can be constructed from any number of separate components such as text from location on a first page of each output PDF document, text that matches a specific text pattern, auto-incrementing numbers and letters, static text, use page labels and etc.
Output Folders
The plug-in allows specifying either a single output folder location for all output PDF documents or ability to determine different output folders for each document by using text from page and dynamically store output files in corresponding folders. See software manual for details or contact tech@evermap.com for assistance.
Name Prefix
Many different options are available: original input file name, current date, document title, document author, document creation date, number of pages in output document. Prefix is automatically added in front of a generated file name.
Base File Name
Specify base filename (all output file names will start with it). This custom text will be added to the name prefix.
Name Suffixes
Specify any number of name suffixes to automatically append to the filename. It can be either an autoincrementing number or letter, output page range, page label, or text from a document (specified either by position on the first page of each output document or by a text search pattern). AutoSplit™ will automatically increment numbers and letters to create unique file names.
Text From Document (By Location)
It is possible to extract text from each output document and use it as a part of the filename. The plug-in uses a user-specified area on the first page of each output document to retrieve text and uses it as a filename suffix.
Text From Document (By Text Search)
The software can use a search pattern (utilizing a regular expression syntax) to look for a specific text on the first page of each output document and use it as a filename suffix. This is a very powerful method for naming output documents such as invoices, account statements and reports.
Custom File Names
Custom file names can be used for manual page ranges method. This is because a number of output files is known in advance. Custom file names can be combined with a name prefix and a base filename as well.
Create Folders
AutoSplit can create folders on a disk that mirror the bookmark tree structure of the input document. This option is useful for documents with complex bookmark structures and when a better file organization is desired. All output documents are instantly organized into appropriate folders. Bookmark names are used for naming disk folders resulting in human readable file structure. This option is available only when splitting by bookmarks.
New! Post Processing Using Acrobat JavaScript
Use the plug-in to execute custom Acrobat JavaScript code on each output PDF document. This feature is useful when it is necessary to perform certain modifications to the output PDF documents such as insert a common cover page, add footer/header, add watermarks, apply security policies or save files into different folders based on user-specific logic. The use of Acrobat JavaScript provides an excellent tool for customizing document splitting for your particular processing needs.
New! Post Processing with Command-Line Scripts
The plug-in provides ability to execute a custom command-line script (as used in BAT files) at the end of splitting process. Use this functionality to perform custom file-level maintenance on output files such as check-in files into a corporate document management system or archive documents into a ZIP file.
Document Merging
Merge Files From Multiple Folders Into Multiple PDF Files
This merging operation allows creating multiple output files by merging files from multiple input folders. Each output file is created by taking one file from each input folder and merging them together. Files are merged based on filenames. For each file in the first input folder, there is one output file (with the same name) created in the output folder. Documents are combined by searching for the most similar file names in each input folder and appending them to the output file. Each file name is compared to the name of the current output file and the filename with the longest match is used (click here for the visual diagram). This method can be used to assemble multiple personalized documents (for example, montly statements) from multiple sub-documents.
Merge PDF Documents With Similar Filenames
Use this method to merge multiple PDF files into multiple output documents based on filename similarity. Each output file is created by taking one input document and finding all other documents that have at least X common first characters in the filename. The similarity between two filenames is controlled by a user-specified number of characters. For example, use this merging method to combine documents based on first 16 characters of the filename:
Files are sorted alphabetically prior to merging. The order of the files in the merged document(s) depends on the document names. The names of the output documents depend on what filename appears first in the sorted list of input files. Here is an example of merging 8 files into 2 output PDF documents:
Merge Multiple PDF Documents Into One
Easily merge multiple PDF documents (or files in any supported file format) into a single one. All pages or just a selected subset of pages (page range, odd/even pages) are copied from each input document. The first page from each document is automatically bookmarked with a file name or a custom user-specified text. (View a screenshot of the document merging dialog).
File Formats
Any suppported file format can be used in a merge operation. You can merge PDF documents, various image files such as TIFF and JPEG, Microsoft Word Documents and etc. The actual list of supported formats depends on the particular version of Adobe Acrobat.
Append Pages
Pages from multiple input documents are sequentially copied (appended) into a new output document. The user can optionally specify a range of pages to use from each input document.
Interleave Pages
Pages from multiple input documents are sequentially interleaved and copied into a new output document. Software proceeds as follows: first N pages from first document are copied to the output, and then M pages from the second document are copied and so on. This process is repeated until all pages are processed. For example, if document A (200 pages long) is interleaved (every 4 pages) with document B (100 pages long, interleave every 2 pages) then software will repeat pages from document B as many times as necessary to complete this task. The output document will look like the following:
Pages 1-4 from document A
Pages 1-2 from document B
Pages 3-6 from document A
Pages 3-4 from document B
Pages 7-10 from document A
....
Pages 196-200 from document A
Pages 99-100 from document B

User can optionally specify a range of pages to use from each input document and number of pages to interleave from each document.  
Reverse Page Order
Page order of any input document can be optionally reversed during the merge process. For example, after scanning 10 pages of a two-sided document you may end-up with two different PDF files: one for odd (1,3,5,...) and one for even pages (10,8,6,...). However, the “even-pages” document has a reverse page order. These two documents can be merged into a single PDF file while page order of the “even-pages” document is reversed on the fly creating output document with correct page order (1,2,3...).
Merge Odd/Even Pages
Software allows optional selection of a page subset (all pages, even pages only, odd pages only) for each input document. For example, you can merge odd pages from one document with even pages from another.
Merge All Files in a Folder
Folders can be used as input for document merging procedures. All PDF documents from a folder will be merged including content of the subfolders (optionally). Files can be sorted alphabetically before merging. Blank page can be optionally added to the end of any input document that has an odd number of pages. This feature ensures that the first page of each input document will start on the even page in the output document.
Transfer Bookmarks and Links
The plug-in transfers bookmarks from input documents and updates links to make them point to correct pages in the merged document.  
Sort Input Files
The merging order of input documents can be changed by alphabetically sorting file names.
Import / Export of Document Names
The plug-in provides powerful import and export capabilities from a comma-delimited text file. Save time by importing an existing document list from an existing spreadsheet or a database. Use Excel or any other software of your choice to create a list of documents to merge and then easily import it into AutoSplit. Optional page ranges and custom bookmark titles can be specified as well. (View a sample of the import/export file format).
Save Settings for Future Reuse
Save and reuse complex document merging settings to save time and increase productivity. All application options including input document names can be saved into a file for future reuse.
Merge Documents Using Control File
Use Plain Text Control File
Merge one or more files (PDF or any other supported file format) into one or more PDF documents using a plain text control file. This method provides a flexible way of merging files into multiple PDF documents with precise user control.
Automatic Renaming of PDF Files
How it Works?
Use this advanced feature to automatically turn nameless PDF files into human-readable filenames according to your document processing requirements. Instantly rename multiple PDF files by using document text and metadata in the filenames. Review auto-generated names before files are actually renamed. This features is a big time saver!
Processing Workflow
Specify filenaming scheme, Select input PDF files, Software computes filenames, Review and edit proposed filenames, Confirm and rename PDF files
File Naming Components
Automatically rename multiple PDF files by using any combination of the following elements:
  • Original document filename
  • Text extracted from a specific location on the page
  • Text or pattern extracted by performing advanced search operation (regular expression are supported)
  • Auto-incremented number (custom starting/incrementing parameters, optional leading zeroes)
  • Auto-incrementing letter
  • Page label (from the first page of the document)
  • Any custom text
  • Document metadata property such "Author", "Subject, "Title" or page count
  • Current time: year, month, day, hour, minute, second
  • The name of the currently logged Windows user
  • The name of the computer 
Updating PDF Documents By Inserting and/or Replacing Pages
Updating Multiple PDF Documents
The software provides a spreadsheet-like interface for inserting and/or replacing pages in one or more "target" PDF documents from one or more "source" PDF documents. This operation is useful when a large set of PDF documents needs to be updated by inserting or replacing certain pages. Pages can be referred to by pages numbers, page labels, bookmarks and named destinations. This provides a great flexibility in identifying pages that need to be updated. All updates are applied simultaneously, so there is no need to account for page number changes as a results of multiple page insertions or replacements. For example, it is possible to replace 2 pages starting at page label “ii” in document “A.pdf” with 3 pages starting at page pointed by bookmark "Chapter 4" in document “B.pdf”.
Automatic Generation of Page Labels By Text Search
Use this operation to search each page in the PDF document for the selected or custom page label style(s) and creating page labels if a matching text is found. Page labels are used by Adobe Acrobat in the “Thumbnails” navigation panel and in the "current" page entry. Page labels allow naming PDF pages using any combination of letters and numbers. The text search and matching is performed inside one or more user-defined "search area" on the page. Custom search patterns can be specified using regular expression syntax. This operation is very useful for adding page labels to files for use with "Update Documents" operation.
Extracting File Attachments
Extract All Embedded Files
Extract all embedded files from one or more PDF documents simultaneously. The plug-in can process regular PDF files as well as PDF portfolios (introduced in Acrobat 8). All embedded content is saved into a user-specified folder. The HTML (with hyperlinks to extracted files) and CSV report files are generated automatically and include the following metadata: file name, description, size in bytes, creation and modification date/time, MD5 checksum. The plug-in adds "Extract Embedded Files" command to the Adobe Acrobat batch processing framework (available in Adobe® Acrobat® Professional).  
Export Embedded Files Metadata
The plug-in allows exporting embedded files metadata for many files at once without extracting any embedded content. The software supports two formats that can be easily imported into any spreadsheet application: text (CSV) and MS Excel XML files. Metadata includes any standard or custom fields such as file name, description, size in bytes, MD5 checksum, creation and modification date/time. If a PDF portfolio was created by Microsoft Outlook ("Convert To Adobe PDF" menu) email application, then each file might have the following metadata fields (specific to email): "Subject", "From", "To", "Cc", "Attachments", "Folder", "Received", "Importance", "Sensitivity" and etc.

«I was tasked with archiving over ten years’ worth of financial reports for our school districts, which involved splitting and indexing literally hundreds of thousands of composite PDF reports for purchase orders, W-2’s, 1099’s, check registers and so forth. Evermap’s AutoSplit Pro did the job well-enough when I first tried it, but I wasn’t quite satisfied with how it was naming the output files. In three or four e-mail exchanges with their tech support, I explained how I thought the product should work, and unbelievably, these improvements were included in an elegant product update within just a couple of weeks! Where in the technology world does THAT happen?! I love this company and its products.»
