Redact PDF
Draw black boxes over anything sensitive. On save, affected pages are re-rendered as images with the boxed content gone — unlike a drawn rectangle, the text underneath is not recoverable.

Frequently asked questions
Are my PDF files uploaded to a server?
No — this tool runs entirely in your browser using WebAssembly and JavaScript. Your files never leave your device, which also means there are no size limits and no queues.
Is the redacted content really removed?
Yes. Pages containing redactions are converted to flat images with the boxed areas blacked out, so the underlying text no longer exists in the file. The trade-off: those pages lose selectable text.
