Split Documents at Pages Where Page Size or Orientation Changes
Manually dividing a large PDF into individual files containing fewer pages can be a slow process. The AutoSplit™ plug-in offers a way to identify where pages of a document change orientation or overall size, and split it into separate smaller documents.
The tutorial steps below demonstrate how to carry out this procedure on an input document containing groups of portrait and landscape pages. The goal is to split it into multiple files that contain pages of the same orientation. Every time a change in size/orientation is detected, the following pages are extracted into a separate file, and so on.

Input Document Description
The input document used in this example is a PDF file containing groups of portrait and landscape pages:
sample input document
The two page types feature completely different page content. All portrait pages contain sample payslips. All landscape pages contain sample timecards stating hours worked and general employee information. They are ordered in the document as pairs - x2 payslips and x2 timecards for each employee. After splitting the document, output files will contain only payslips and timecards for a single person. The names that feature on each page will also be extracted and used to name them.
input document content
You need a copy of Adobe® Acrobat® along with the AutoSplit™ plug-in installed on your computer in order to use this tutorial. Both are available as trial versions.
Step 1 - Open the "Split Document Settings" Dialog
Select "Plug-Ins > Split Documents > Split Document..." from the main menu to open the "Split Document Settings" dialog.
open split settings
Step 2 - Configure the Splitting Method
Under "Split Method", check "Use separator:" and select the "Page Where Size Changes" option from the drop-down list of separator types.
select split method
Step 3 - Edit Tolerance Settings
Press the "Options..." button.
open tolerance options
Use this dialog to modify a 'tolerance' amount for identifying changes in page size. The default tolerance is 40mm - the PDF will be split at pages where changes in width or height are greater than this amount. For example, reducing this figure to a much smaller amount would mean that page size is considered to be 'different' with only subtle differences.
In this example, the input PDF only contains standard portrait and landscape A4 pages. Width and height exceed a 40mm difference between the two page types.
Press "OK" to proceed.
confirm size tolerance
Step 4 - Choose an Output Folder
Press the "Browse..." button to choose an output location for the split files.
browse output folder
Locate and select a suitable folder, then press "Select Folder".
select output folder
Step 5 - Configure a File Naming Scheme
Use the file naming section to configure a naming scheme for output documents. Optionally add a name prefix, base filename - or one or more custom filename components by pressing "Add...".
create filenaming scheme
In this example, output files will be named with an "N_AnnJohnson" format. Each starting number corresponds to a group of matching page sizes that have been extracted from the input document. First and last names will be extracted from the first page of each extracted 'group' of matching page sizes.
For instance, the first two pages of the input document are portrait and contain payslips for "Ann Johnson". The third page is a horizontal timecard, so the first two pages will be extracted separately.
This configuration searches for the presence of the text "First:" and "Last:", and extracts any text that follows (all payslips and timecards feature the employee name in this format). The output filename for the first output document following this split operation will be "1_AnnJohnson.pdf".

Step 6 - Optional: Save and Reuse Settings
Press "Save Profile..." to save these settings. They can be loaded later via the "Load Profile..." button, to process future documents using the same method. Settings will be saved with an *.apr file extension in the chosen folder.

Step 7 - Split the Document
Press "OK" to split the document.
confirm settings
Press "OK" again to confirm the procedure.
confirm split
Step 8 - Check the Results
A results dialog lists the output files that have been created. Press the "Open Output Folder" button to view them.
view output results
Check the contents of the chosen output folder. Open a file in Acrobat to inspect its contents.
open output document
The input file has been split into x4 documents containing pages of the same orientation.
Output breakdown:
File "1_..." = Ann Johnson's payslips (portrait).
File "2_..." = Ann Johnson's timecards (landscape).
File "3_..." = Linda Anderson's payslips (portrait).
File "4_..." = Linda Anderson's timecards (landscape).
check output pages
Batch Processing
Use Action Wizard tool to run splitting on multiple files at once or on all files in folder. This functionality is available in AutoSplit Pro and Acrobat Pro versions.
