Redact PDF

About this Tool

Redact PDF online free — permanently remove sensitive information before sharing

You need to share a document. But it has a phone number, an Aadhaar number, a client name, or financial details that shouldn't be visible to the recipient. Putting a black box on top isn't enough. The text is still in the file — anyone can remove the overlay and read it. TruePDFs Redact PDF tool removes the content permanently. Free, browser-based, no installation.

What this tool does

You type the exact words, numbers, or phrases you want removed. The tool scans your PDF, finds every match, and covers them with black rectangles — permanently. The underlying text is gone from the file structure, not just hidden on screen.

Who needs this?

Legal professionals

Sharing contracts or case documents with parties who should only see parts of the file. Redacting names, case numbers, or personal details before sending.

Businesses handling client data

Removing client PAN numbers, bank details, or contact information from reports before sharing internally or externally.

HR and finance teams

Salary documents, appraisals, and financial records shared across departments — redact what each recipient doesn't need to see.

Anyone submitting government documents

Forms that contain Aadhaar, PAN, or account numbers that need partial redaction before public filing or third-party submission.

Is redaction reversible?

No. Proper redaction permanently removes the data from the PDF file — not just visually, but from the underlying file structure. Once you download the redacted PDF, that content can't be recovered. Keep a copy of the original before redacting.
