•Password-protecting confidential contracts, financial reports, or personal documents
•Unlocking PDFs you own but can't edit due to forgotten passwords or restrictions
•Sanitizing documents to remove author information, comments, and revision history before public release
•Setting permissions to prevent unauthorized copying, printing, or editing of proprietary content
•Removing security from old archived files to enable modern workflow integration

•All security operations are performed locally - passwords and files never leave your browser
•Strong passwords are essential - use a mix of letters, numbers, and symbols for best protection
•Unlocking PDFs requires the correct password - these tools cannot crack or bypass unknown passwords
•Sanitization removes metadata permanently - keep original files if you need to preserve document history
•Password protection is not encryption - for highly sensitive data, consider additional security measures
