Redact a PDF
Draw black boxes over private details. Redacted pages are flattened, so the covered text is truly removed — not just hidden.
Pages with redactions become images, so the hidden text is really gone.
Files stay in this browser tab. Close the page and they are gone.
How it works
- Add the PDF.
- Drag on the pages to cover what must be hidden.
- Download the redacted PDF.
Questions
Is the information really removed?
Yes. Every page with a redaction is turned into an image with the black boxes burned in, so the covered text and pictures are gone from the file.
What happens to the other pages?
Pages without redactions are kept exactly as they are, with selectable text.
Are my files uploaded anywhere?
No. The tool runs entirely in your browser, so your files never leave your device and nothing is kept after you close the page. You can check it yourself: once the page has loaded, turn on airplane mode — the tool keeps working.
Is it free? Is there a file limit?
Yes, it is free, with no sign-up and no watermark. There is no upload limit because nothing is uploaded; very large files are limited only by your device’s memory.
