Frequently asked questions
Is it safe to type a password into an online PDF tool?
Here, yes - the document and the password are processed entirely in your browser by an encryption engine running on your own device. Neither ever leaves your computer, which is exactly what you want before protecting a sensitive file.
How strong is the encryption?
The PDF is encrypted with AES-256, the same standard modern PDF readers use for their strongest protection. Anyone opening the file in Adobe Reader, Preview, a browser, or a phone will be asked for the password first.
What happens if I forget the password?
The document cannot be recovered - AES-256 has no practical workaround, and there is no reset because nothing is stored anywhere. Keep the password in a password manager, and keep an unprotected copy of the file somewhere safe if you can.
