How Redact PDF Works

Before sharing contracts, bank statements, or official records for legal filings or portal submissions, simply drawing a dark rectangle over private details is not enough because hidden text can still be copied underneath. Our Redact PDF tool searches your document for specific names, phrases, phone numbers, email addresses, credit cards, and IBANs, permanently stripping the underlying text layer and replacing it with a solid black, gray, or white redaction bar. Everything runs locally in your browser so confidential files never leave your device.

FREQUENTLY ASKED QUESTIONS

Redact PDF FAQs

Can someone copy or recover the text under a redacted box?

No. Unlike simple drawing tools that only cover text visually, this tool removes the underlying text layer so redacted content cannot be selected, searched, or copied.

Can I redact multiple words and numbers at the same time?

Yes. Enter as many comma-separated names or terms as you need and combine them with automatic pattern checkboxes in a single pass.

Are my confidential documents sent to a server during redaction?

Never. All text scanning and redaction happen locally inside your web browser memory.
