Lock a PDF with a password so only people who know it can open it, and choose whether they can print, copy or edit. Private and in your browser.
If you forget the password, nobody — including us — can recover the file. Keep it safe. Some PDF apps ignore the print, copy and edit limits; the open password is the strong protection.
The PDF is encrypted with AES-256, the standard strong method. Pick a long password you don't use elsewhere.
It cannot be recovered by anyone, including us. Keep a copy of the original and the password.
Some PDF apps ignore them. Only the open password truly keeps people out.
No. This tool works entirely in your browser, so your PDF never leaves your device.
