About the PDF Password Protector & Remover
Protect a PDF with a password, or remove one you already know. Protection uses the standard 128-bit (RC4, revision 3) security handler that opens in Acrobat, Preview and most readers. Removal opens the file with your password and rebuilds it without encryption. To keep everything offline, both operations regenerate the PDF from rendered pages.

Frequently asked questions
Can this remove a password I don’t know?+
No. You must supply the correct password. The tool cannot and will not bypass unknown PDF passwords.
Which encryption standard is used?+
The standard security handler with 128-bit RC4 (revision 3), which is widely supported by PDF readers.
Why does the text become non-selectable?+
To encrypt offline without a server, pages are rebuilt from images. If you need selectable text, keep an unencrypted master copy.
Is the password sent anywhere?+
No. Encryption and decryption run in your browser; the password is used locally and never transmitted.
