Frequently asked questions
- How do I use the Unlock PDF tool?
- Select a PDF from your device, adjust any options shown, then click the action button. The result downloads immediately. If the PDF is password-protected, use the Unlock PDF tool first.
- What PDF formats are supported?
- Standard PDF files from Acrobat, browsers, Office exports, and scanners are supported. Very large files may be slower on older devices because processing happens locally in your browser.
- Can you crack unknown passwords?
- No. You must know the correct password. This tool removes protection when you supply the password.
- Are my files uploaded to your servers?
- No. This tool runs in your browser whenever possible. Your files and text stay on your device and are not sent to our servers for processing.
