Good to know

  • Pages keep their original size, orientation and content.
  • Password-protected PDFs must be unlocked before merging.
  • Up to 100 MB per file. Very large merges depend on your device’s memory.
  • Your file is processed in your browser and is never uploaded. How this works.

Merge PDF FAQ

Is there a limit on how many PDFs I can merge?

There is no fixed file count. Each file can be up to 100 MB, and the practical limit is your device’s available memory.

Can I change the page order inside a file?

Merge PDF orders whole files. To drop or reorder pages first, use Extract PDF Pages or Delete PDF Pages, then merge the results.
