Redact PDF — Black Out Sensitive Text Free
Permanently remove sensitive text from PDFs — names, ID numbers, financial details. Redactions are flattened into the file, so the hidden text is truly gone, not just covered. The only safe way to share documents containing information others must not see.
How to redact a PDF
Open your PDF in the Redact tool.
Select the text or areas to redact.
Apply — selections become permanent black boxes.
Download the redacted PDF.

Tips for best results
Use search-and-redact to catch every instance of a name or account number.
After redacting, re-open the file and try selecting the blacked areas to verify.
Check document metadata separately — author and title fields aren't content.
Redact before sharing, not after — assume any shared copy is permanent.
Frequently asked questions
Is the redacted text really gone?
Yes. True redaction removes the underlying text from the file and flattens the black boxes — unlike drawing a black rectangle over text, which anyone can delete to reveal what's beneath.
What's the difference between redacting and just covering text?
Covering (e.g. a black shape in an editor) hides text visually but leaves it in the file — copy-paste or deleting the shape exposes it. Redaction deletes the content itself.
Can I redact the same word everywhere at once?
Yes — search for a term (like a name or account number) and redact every occurrence in one action.
Does redaction remove metadata too?
Redaction removes the selected visible content. Document metadata (author, title) is separate — check your PDF's properties if that matters.
Is my sensitive document uploaded?
No — redaction happens locally in your browser, which is exactly what you want for sensitive files.
