About this tool

Sanitize PDF tool removes all hidden data, metadata, scripts, and embedded content from your PDF files comprehensively. This ensures your documents are clean and safe to share, protecting your privacy and preventing information leakage. The tool removes author information, creation dates, modification dates, software used, comments, annotations, form field data, JavaScript, embedded files, and other hidden content. This is particularly important when sharing documents publicly, submitting documents to third parties, or when privacy is a concern. The sanitization process preserves all visible content, text, images, and formatting while removing all hidden and potentially sensitive information. All processing happens locally in your browser, ensuring your documents never leave your device during the cleaning process. The resulting sanitized PDF maintains high quality for visible content and can be downloaded immediately after processing. Perfect for professionals sharing documents publicly, students submitting assignments, or anyone who wants to ensure their PDFs contain no hidden information before sharing.
