About Unlock PDF

Upload a password-protected PDF, enter the correct password, and download an unlocked version with all security restrictions removed. The tool uses pdf-lib to load the encrypted PDF with the supplied password and then saves a clean, unprotected copy — all entirely in your browser. No files leave your device. Only use this tool on PDFs you own or are authorised to unlock.
