FAQ

Is there a file size limit? Only your device's memory. Very large files work best on a computer rather than a phone.

Will the merged PDF lose quality? No. Pages are copied exactly as they are — nothing is re-rendered or compressed.

Does it work on password-protected PDFs? No — remove the password in your PDF app first, then merge.
