Redact a PDF — and truly remove what's underneath
Draw a black box over any text and DocRazor doesn't just cover it — it rebuilds that page as an image, so the hidden text can't be selected or copied back out. Everything runs locally; your document is never uploaded.
Open your PDF in DocRazor's Redact tool.
Drag a box over anything you want gone — names, numbers, whole paragraphs.
Download a PDF where the redacted text is genuinely unrecoverable.
FAQ
Is the text really removed, or just hidden behind a black box?
Really removed. Many tools just draw a black rectangle on top — the text underneath can still be selected and copied. DocRazor flattens each redacted page to an image, so there is no text left to recover.
Can it find personal data automatically?
Yes — 'Find personal data' scans the whole PDF for names, emails, tax codes, IBANs, VAT numbers and phone numbers and pre-marks them for you to review. It's free to try on the built-in sample document; on your own files it's a PRO feature.
Are my files uploaded to redact them?
No. Redaction runs entirely in your browser's memory — your document never leaves your device.
