Free Unlock PDF
Remove known opening passwords or owner restrictions from one PDF or a batch, without guessing credentials, and verify every encryption-free copy before download. Your upload uses encrypted durable storage when available and a private same-origin processor otherwise. Temporary sources are deleted after each attempt; durable checked results remain recoverable in this browser for up to six hours.

Sign in to save and reopen documentsNo artificial page or file-size limits · resumable encrypted upload · automatic deletionHow it works
- Choose one or more protected PDFs you are authorized to use, or try the local AES-256 sample
- Use one opening or permissions password for the batch, or enter a different known password for each PDF
- Choose web optimization and decide whether signed files must stop safely instead of losing certificate trust
- Download only after every result reports no encryption, opens without a password, preserves every page, and passes visual and structural checks
Short-lived by design
This tool uses open-source processors in a private temporary workspace that is deleted after each attempt. When durable storage is available, uploads are encrypted and resumable and checked results stay recoverable to this browser for up to six hours. If that storage is unavailable, the same-origin fallback returns the checked result directly. Failed or cancelled job files are removed immediately. Account storage is used only when you explicitly choose Save to Bookify.
