Merge PDF


The Merge PDF rule allows you to combine two or more .pdf files together. It is also possible to combine image files to the PDF file, for example .png or jpg. This rule can be useful when creating one large PDF document from smaller files. The generated file name will be the same as the first file used to merge, see image below for an example:

When to use

Use this rule when your process requires you to merge dynamically two or more PDF files. For example automatically merge expense receipts submitted by users into a single PDF files containing all images or PDF receipts.

You can add this rule:

  • to a field
  • to a form
  • to a process (the rule will run on load)

The rule also requires at least 3 file fields, which are used to select files that you want to merge and a file field to store the merged PDF. To learn how to add a file go to File upload control.

  • File field (To be merged file #1) - used to hold the first file that you want to merge.
  • File field (To be merged file #2) - used to hold the second file that you want to merge.
  • File field (Merged PDF file) - used to store the merged PDF version of the two files.
