A straightforward PDF unlock tool that does one thing well: removes password protection from encrypted PDF files. No bloated feature sets, no subscription prompts, no upsells. Upload the protected PDF, type the correct password, and download the unlocked version. The tool uses the Web Crypto API for hardware-accelerated decryption, supports both AES-256 and RC4 encryption standards, and runs entirely in your browser. There are no server uploads, no file size restrictions, and no limits on how many files you can process. The interface is intentionally simple — one file, one password, one click. If the password is wrong, you get a clear error message (not a corrupted file). If the PDF is not encrypted, the tool tells you so immediately. It is designed for people who just need to get the job done without wrestling with complex software.

## 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

- **Quick One-Off Unlocking**: You received one encrypted PDF and need to unlock it. No need to research, install, or subscribe to anything — just use this tool and move on.
- **IT Help Desk**: Help desk staff can use this tool to quickly unlock PDFs for employees without installing additional software on help desk machines.
- **Cross-Department Requests**: When departments share protected documents, admin staff can unlock them using the provided password and redistribute as needed.

## Tips

- **Simple Workflow**: Upload → Enter Password → Download. That is the entire process. No settings to configure, no options to choose.
- **Error Messages Matter**: If the tool says 'incorrect password,' double-check for typos, extra spaces, or caps lock. PDF passwords are case-sensitive.
- **Works Offline After Load**: Once the page loads, the decryption engine works without internet. Useful for privacy-conscious users who want to disconnect before processing.
