Questions
Are my PDFs uploaded anywhere?
No. Merging happens inside your browser on your own phone or computer. The files never reach our server.
Is there a limit on files or size?
There is no fixed limit. Very large files (over about 100 MB in total) can be slow or fail on phones with little memory. A computer handles them better.
Why does it say my PDF is password-protected?
Some PDFs are locked by their creator. Open the file with its password and save a copy without protection, then try again.
Does it add a watermark?
No watermark, no sign-up, and no limit on how many times you use it.
