Frequently asked questions
What does protecting a PDF actually do?
It encrypts the file with a password and lets you restrict actions like printing, editing or copying for anyone who doesn't have the password.
Is my password sent anywhere?
No, the password and the encryption both happen entirely in your browser — neither the file nor the password is ever uploaded.
Can I choose what other people are allowed to do with the file?
Yes, under 'Additional options' you can individually allow or block printing, editing, copying, form filling and more.
What if I forget the password I set?
There's no way to recover it — the encryption is real, so make sure to store the password somewhere safe.
Can I protect multiple PDFs with the same password at once?
Currently protection is applied one file at a time so you can review each document's settings before saving.
