How to Redact a PDF Free — Black Out Sensitive Text Online

True PDF redaction permanently removes text from the file — it is not just a black box covering the text. Upload your PDF, draw redaction boxes over SSNs, names, addresses, or any sensitive content, and download a permanently redacted copy. The text underneath is gone — not hidden, not recoverable.

Redaction vs Black Box — Critical Difference

	True Redaction	Black Box Annotation (NOT Secure)
Text under box	✓ Permanently removed from file	✗ Still in the file, just visually covered
Text selectable	✓ No — text is gone	✗ Yes — can be copied from under the box
Text extractable	✓ No — not in file data	✗ Yes — PDF text extractors find it
Safe for legal/compliance	✓ Yes	✗ No — multiple data breaches from this mistake
Reversible	✓ No — permanent	✗ Yes — remove the annotation to reveal text
PDF file structure	Text data removed from content stream	Text data intact, annotation layer added

Warning: Using Adobe Reader's highlight or rectangle tools to "black out" text is NOT redaction. The text is still in the PDF. Multiple government agencies and law firms have accidentally leaked SSNs and classified information this way. Always use a true redaction tool.

How to Redact Your PDF

1. Upload your PDF — drag and drop or click to select. The PDF loads in your browser (not uploaded to any server)
2. Draw redaction boxes — click and drag to draw black rectangles over any text you want to redact. Cover SSNs, names, addresses, phone numbers, or any sensitive content
3. Review your redactions — scroll through the document and verify all sensitive information is covered
4. Download the redacted PDF — the tool creates a new PDF with the text permanently removed under each redaction box
5. Keep the original — store the unredacted original securely. Redaction is irreversible

Common Use Cases

• Legal filings: Court documents often contain personal information that must be redacted before public filing

Privacy: Why Local Processing Matters for Redaction

Documents that need redaction contain the most sensitive information you own — SSNs, financial data, medical records, legal information. Uploading these to a server-based redaction tool means your most sensitive document travels through the internet and sits on someone else's server, even temporarily.

Browser-based redaction: your PDF stays on your device. The processing engine loads in your browser and runs locally. No upload, no server, no one else sees your document.
