When and how to use Merge PDF

Merge PDF is built for combining multiple PDF files in the right order before delivery, submission, or archive handoff.

The key controls on this page are Mode, Optimize After Merge. Check them before you process final files.

If this run affects client delivery, approval, or archive quality, validate the output once before you share it. The related how-to and use-case pages below cover the most common real-world edge cases.

Best practices

  • Confirm file order and page orientation before the final run, especially when combining reports, appendices, or signed pages.
  • Use balanced defaults first, then increase processing strength only when required.
  • Validate output readability on both desktop and mobile before sharing.

Common issues

  • Mixed page sizes, hidden blank pages, or wrong file order can make the final combined PDF look inconsistent.
  • Range syntax errors can skip required pages.
  • Large scans can remain heavy until OCR and cleanup are combined.
