Redact PDF Online Free
Sharing a document but need to hide the sensitive bits? Type the names, phone numbers, addresses, or ID numbers to conceal, and every occurrence is permanently covered with a solid black box. Ideal for contracts, legal filings, medical records, and public disclosures. Because it all happens in your browser, confidential documents stay confidential. After redacting, verify before sharing: try selecting the covered text — if you can still copy it, it is not hidden yet. Also strip identifying metadata from the file before sending it anywhere.

Frequently Asked Questions
Is the redaction truly permanent?
The matched text is covered with opaque black boxes burned into the page content. For maximum safety with highly sensitive documents, always double-check the output before sharing.
Can I redact a whole paragraph?
Enter the exact phrase on one line and every occurrence will be boxed out. For long passages, list the key identifying terms.
Does redaction work on scanned PDFs?
Scanned PDFs are images without a text layer, so text search cannot find matches. Run scanned documents through the OCR tool first, then redact the result.
Is matching case-sensitive?
No — redaction matching ignores case, so "John Smith" will also match "JOHN SMITH".
Are my files uploaded anywhere?
No. Everything runs inside your browser; your documents never leave your device.
