Merge PDF files on your phone
Combine two or more PDFs into one file in the order you choose. Nothing is uploaded: the merge runs on your phone and works offline.
How it works
- Open Merge and pick your PDFs
- Drag the pages into the order you want
- Tap Run — the merged PDF is saved to Files

Questions
Is there a limit on the number of files?
Free accounts get five documents a day across the on-device tools; Premium removes the cap. The pages keep their original quality.
Is it free?
Yes. On-device tools are free: five documents a day, no account. Cloud tools have a free daily allowance; Premium removes both limits.
Where does my file go?
On-device tools never send it anywhere. Cloud tools upload it over an encrypted connection and delete it within 60 minutes.
