  • Contracts: keep the main document and its attachments together.

Tips for a tidy merged PDF

  • Check the order before you merge, since changing it afterwards takes extra steps.
  • Starting from pictures? Use Images to PDF to combine JPG to PDF, or PNG to PDF, then merge the results.
  • Starting from Word? Convert with Word to PDF first.
  • Fix the result later. Organize PDF lets you reorder, delete or extract pages.
  • Make it smaller. Large merged files can be reduced with Compress PDF before you email them.
  • Add a password with Protect PDF if the document is private.
