How to password protect a PDF
Updated · 3 min read
Lock a PDF with a password before you share it, and remove the password later when you no longer need it.
Try it now: choose a file and it opens in Lock PDF.
Bank statements, ID copies and salary slips travel by email and chat, where they can be forwarded. A password means only people who know it can open the file.

Share the password safely
- Send the password through a different channel than the file, for example by phone call or a separate message.
- Use at least 8 characters, mixing letters and numbers.
- Keep the password somewhere safe. A forgotten password can’t be recovered.
Remove the password later
If you know the password, Unlock PDF saves a copy that opens without one. It can’t open a PDF whose password you don’t have.
Locking happens inside your browser, so neither the file nor the password is sent to us.
