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.

## How it works

1. **Upload Encrypted PDF** — Select or drag and drop the password-protected PDF file you want to unlock.
2. **Enter the Password** — Type the user or owner password that was used to encrypt the PDF file.
3. **Download Unlocked PDF** — Get a copy that opens freely without any password prompt. All content preserved.

## Use cases

- **Student Budget**: Students often receive password-protected course materials. Unlock them for free without paying for desktop software or cloud subscriptions.
