Questions
Is there a limit on how many PDFs I can merge?
No fixed limit. Free files can be up to 25 MB each; Pro raises that to 1 GB.
Do my files get uploaded?
No. ZoungPDF merges your files directly in your browser, so they never leave your device.
Is ZoungPDF free?
Yes. Merge, split, compress, organize, rotate and convert are free. ZoungPDF Pro unlocks watermarks, page numbers, password protection, signatures, batch processing and files up to 1 GB.
Are my files safe?
Your files are processed entirely inside your browser. They are never uploaded to our servers, so nobody else can see them.
