Black out names, account numbers and other private details in a PDF. Redactions are burned into the page so hidden text cannot be copied back out.
Redact PDF permanently blacks out names, account numbers and other sensitive details in a document by burning the redaction into the page itself, rather than just drawing a black box over the top that hidden text could later be copied out from underneath. It's built for exactly the situations where a simple visual cover-up isn't good enough — contracts, medical records and bank statements being shared with someone who shouldn't see every detail.
Mark the areas you want to redact directly on the page preview, and the tool flattens that region into the page render so the underlying characters are gone, not merely obscured. Because everything happens locally in your browser, the sensitive document never has to be uploaded to a third-party redaction service just to remove a few lines of private information.
Redacted areas are flattened into the page render, so the underlying text is gone completely rather than hidden beneath a rectangle that could be selected and copied.
The document never leaves your browser, which is exactly what's needed for contracts, medical records and bank statements containing sensitive personal data.
Draw redaction boxes exactly over the text or detail that needs removing, rather than covering an entire page or section unnecessarily.
No. The redacted area is flattened directly into the page's rendered content, meaning the underlying characters are removed entirely rather than simply covered by a rectangle that could later be deleted or the text copied out from beneath.
No. Redaction happens inside your browser, keeping the process local for exactly the kind of documents where that matters most — contracts, medical records and financial statements.
Zoom in on the page before drawing a redaction box to make sure it fully covers the target text with a small margin, since a box that's slightly too small can leave the edge of a character or digit visible in the final flattened page.
No. The area is flattened into the page render, so the underlying characters are gone rather than simply covered by a rectangle.
