Redact PDF
Draw black boxes over sensitive content and permanently flatten the page so the hidden content cannot be recovered.
About this tool
Draw black boxes over sensitive content and permanently flatten the page so the hidden content cannot be recovered. It runs entirely in your browser using open-source PDF libraries, so your document is processed on your own device and never uploaded to a server. That makes it a fast, private option any time you need to permanently black out sensitive areas of a page.
How to use it
- Upload a PDF.
- Draw black boxes over any sensitive text or images.
- Download the flattened, permanently redacted PDF.
Tips
- Redaction here is a real flatten, not just a black rectangle drawn on top — the content underneath can't be recovered.
- Zoom in before finalizing to make sure your redaction boxes fully cover the sensitive area.
FAQ
Can the redacted text still be selected or searched afterward?
No, this flattens the page so the covered content is permanently gone, not just hidden.
