Questions
How do I password-protect a PDF?
Drop a PDF, enter a password and confirm it, then tap Protect PDF. Download the encrypted file. Recipients need the password to open it.
Is my PDF uploaded when I protect it?
No. Encryption runs on your device. The file and password never leave your browser for this tool.
Can InstantPDFEdit recover my password?
No. We never see your password. If you forget it, you will need an unprotected copy of the original file.
What kind of protection is this?
User-password encryption so opening the PDF requires the password. It is not a substitute for full enterprise DRM or permission policies beyond what the PDF encryption supports here.
How do I remove a password later?
Use Unlock PDF with the correct password to download an unprotected copy. Only do that if you are allowed to remove protection.
