Questions
Is there a limit on how many PDFs I can merge?
There's no set limit. Because merging happens on your device, very large files depend on your device's memory. Most phones handle a few hundred pages easily.
Will merging lower the quality?
No. Pages are copied as they are, so text stays sharp and searchable and images keep their original quality.
Why won't one of my PDFs open?
Password-protected PDFs can't be merged until the password is removed. Open the file in your PDF reader, enter the password, save a copy without protection, and try again.
Are my files uploaded?
No. Readily reads and combines the PDFs inside your browser. Nothing is sent to a server.
