Why Use SonuPDF to Unlock PDFs?
In-Browser Decryption
Your files are decrypted directly on your device. In contrast to other services, your documents never upload to a cloud server, making this the most private way to unlock sensitive PDFs.
Multiple Unlock Modes
Choose between 'Preserve Quality' to keep selectable text and vector shapes, or 'Convert to Images' for a rasterized version that handles complex permission locks.
Cross-Platform Compatibility
Works on any device with a modern web browser—Mac, Windows, Linux, iOS, or Android. No installation required.
No File Size Limits
Since processing happens locally in your browser's memory, you are not restricted by cloud upload limits or subscription tiers.
