Redact PDF Online — Free PDF Redaction Tool
Black out sensitive areas
Sharing documents often requires hiding sensitive information such as names, addresses, financial data, or personal identifiers. Our free PDF redaction tool lets you draw black boxes over any area of any page to permanently cover content before sharing.
Unlike simply highlighting in black, proper redaction ensures the underlying text is not recoverable. Process everything in your browser so sensitive documents are never uploaded to any server — an essential requirement when dealing with private or confidential information.
How to Redact
- Upload the PDF containing sensitive information.
- Draw redaction boxes over the areas you want to black out.
- Preview the redacted pages to confirm coverage.
- Click Apply and download the redacted PDF.
