How to redact a PDF
- Drop your PDF to see its pages.
- Drag black boxes over anything that must go. Undo if you overshoot.
- Click Redact and save. Pages with boxes are flattened so the hidden content cannot be recovered.
Frequently asked questions
Is this real redaction or just a black box?
Real redaction. Each redacted page is re-rendered as an image with the boxes burned in, so the original text and graphics underneath are gone from the file.
Does the whole document lose its text?
No. Only pages that contain a redaction box are flattened; untouched pages keep their selectable text.
Can I search for words to redact automatically?
Not yet. Draw the boxes by hand; use the zoom in your browser for precision.
Are my files uploaded anywhere?
No. The whole tool runs inside your browser using JavaScript. Your files stay on your device, nothing is sent to a server, and nothing is stored. You can even use it offline once the page has loaded.
Is it really free?
Yes. There is no account, no watermark, no file-size tier and no daily limit. Use it as often as you need.
