Black out sensitive information for good. Marked areas are flattened into the page, so the underlying text is permanently destroyed — never just covered.

How to securely redact a PDF
Upload your PDF document. Your file stays on your device and is never sent to a server.
Click and drag to create black boxes over any sensitive text, numbers, or images you wish to hide.
Click Export. The tool flattens the file, destroying the text underneath the black boxes so it can never be recovered.
Frequently asked questions
Simply upload your PDF, draw blackout boxes over the sensitive text you want to hide, and click redact. The tool permanently flattens the boxes into the document, completely destroying the text underneath.
Yes, absolutely. Because our tool works 100% locally in your browser using WebAssembly, your sensitive documents never leave your device and are never uploaded to any server. It is completely safe for confidential data.
No. Unlike basic editors that just draw a floating box over your text (which can be easily copied), we permanently flatten the PDF to destroy the underlying text entirely. Once exported, it is impossible to recover the hidden data.
No. There are no daily limits, paywalls, or accounts required to use this tool.
