Unlock any password-protected PDF for free. Works with modern AES-256 and legacy RC4 encryption, all inside your browser.
Part of our Unlock PDF Free suite
A completely free PDF unlocker that removes password protection from encrypted PDF files. No watermarks, no page limits, no daily quotas — just enter the correct password and download the unlocked file. The tool supports AES-256 and RC4 encryption, auto-detecting which one was used. Everything runs in your browser using the Web Crypto API, so your file and password never touch a server. Unlike commercial unlockers that charge monthly fees for the same functionality, this tool is and will remain free. It handles the same encryption standards, produces the same clean output, and does so without compromising your privacy by uploading files to cloud servers. The decryption is hardware-accelerated through the Web Crypto API, making it fast even for large files.
