Can I unlock a PDF if I don't know the password?

No. This tool requires the correct password (either user or owner password) to decrypt the file. It does not bypass or crack encryption — it removes the protection once you prove you're authorized.

Will unlocking change the PDF content?

No. Decryption only strips the encryption layer. All pages, text, images, annotations, and formatting remain exactly as they were.

What encryption types are supported?

AES-256 (PDF 2.0, the modern standard) and RC4 40/128-bit (PDF 1.1–1.4, legacy). The tool auto-detects which algorithm was used.

Is my password stored anywhere?

No. Decryption happens entirely in your browser. The password is used locally and discarded immediately — we never see it.

Can I unlock a PDF I encrypted with the Password Protect tool?

Yes. PDFs encrypted with our Password Protect tool use AES-256, which this tool fully supports. Enter the same password you set during encryption.

Free PDF Unlock Tool - Remove Password Protection in Your Browser

You have the password, but every time you open the PDF you have to type it again. Or maybe you need to share the file with someone who shouldn't need to fumble with a password. This tool strips the encryption wrapper from a password-protected PDF so the resulting file opens freely for anyone. It supports both AES-256 (the modern standard) and legacy RC4 encryption. You provide the correct password once, and the decryption runs entirely in your browser using the Web Crypto API — the file and the password never touch a server.
