Encrypt the document with a password that has to be typed before it opens, and set the permissions separately: whether it can be printed, whether text can be copied, whether anyone can modify it. AES-256, applied in your browser — the password never travels anywhere.
This takes a second on the first visit, then it is cached.
Drop in the PDF.
Set the password and tick what you will allow.
Protect and download.
AES-256, the strongest the PDF specification defines. The strength of the result is the strength of your password.
No. Encryption happens in your browser, so the password is never sent anywhere — which also means we cannot help you recover it.
No. Protect PDF runs entirely inside your browser using WebAssembly and the Canvas API — the bytes of your document never travel to us. The only thing that reaches our servers is a counter incrementing by one, and whatever you deliberately choose to save to your library.
Not this one. Protect PDF is part of Baker, at $10 a month — along with the other conversion, compression and security tools, and the AI ones. Signing, editing, watermarking, merging, splitting, rotating, organising and cropping are free, three documents a day up to ten pages each, with no account.
