What Is PDF Redaction?

PDF redaction permanently removes sensitive content from a document by replacing it with opaque boxes. Unlike simply drawing a black rectangle over text, true redaction deletes the underlying data so it cannot be recovered, copied, or searched.

Redaction is a legal and compliance requirement when sharing documents that contain personal information, classified data, or privileged content that must be concealed.

How to Redact a PDF

1. Upload your PDF document.
2. Use the redact tool to select text or areas to hide.
3. Apply redaction marks (black boxes over content).
4. Click 'Apply' to permanently remove content and download.

How It Compares

Adobe Acrobat Pro has a dedicated redaction tool with search-and-redact functionality, but it costs $20+/month. Many people mistakenly use black highlight or drawing tools, which merely cover text visually without removing the underlying data.

This tool performs true redaction, permanently deleting content rather than just hiding it. All processing happens in your browser.

Tips

• Ensure redactions are visible with sufficient opacity
• Redaction is permanent — backup original before applying
• Use for removing personal data before sharing documents

Frequently Asked Questions

Is redaction truly permanent and irreversible?

Yes. Redacted content is permanently removed from the PDF and cannot be recovered or made visible again.

Is my sensitive document kept private during redaction?

Yes. All redaction happens locally in your browser. Your PDF is never sent to or stored on any server.

Can I redact hidden text that's not visually apparent?

Redaction hides visible content. For metadata or hidden text removal, use the metadata removal tool or flatten the PDF.
