PDF Unlock & Lock

Create an unlocked PDF copy when you know the current password, or add a new open password to an unprotected PDF. PDF processing runs on your device. UNLOCK A PDF YOU CAN OPEN Select the PDF and enter its current password. Save an unlocked copy for your own document workflow. The app does not recover, guess or crack unknown passwords. ADD AN OPEN PASSWORD Select an unprotected PDF, enter a new password and confirm it. Save or share the protected copy. Keep the password somewhere safe: the app cannot recover it if you forget it. SAVE AND SHARE RESULTS Select one or more PDFs and process them in sequence. Check each result, then save or share the successful outputs. The source files are not overwritten. When supported, receive a PDF from another Android app’s Open or Share menu. PDF contents are processed locally without uploading them to this app’s server. Advertising, analytics and diagnostic services may communicate online as described in the privacy policy. Sharing an output sends it to the app you choose. Processing access may depend on the available free allowance or rewarded ads.
