Permanently black out sensitive content in your PDFs — entirely in your browser.
The exported PDF contains only image data: no text recovery is possible.
All processing happens entirely in your browser. Your PDF is never sent to any server. Because redacted pages are converted to images, there is no way to recover the original content.
Most PDF redaction tools require you to upload your document to a cloud service. This tool does the opposite — everything runs locally using PDF.js and pdf-lib, so sensitive documents never leave your device. There are no accounts, no subscriptions, and no file-size limits.
