Combine multiple PDFs into one file, in the order you add them. First time? Add files with the big button below, then press Merge — that's the whole process. Free, no signup, no watermark.
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.
