How can I redact a PDF so the hidden text is really removed?
Add your PDF to Lunyce, draw black boxes over the information to hide, then download the redacted document. Affected pages are saved again as images, so the original text no longer exists in the file and cannot be recovered, while other pages stay intact. The PDF is never uploaded, and the tool is free with no account.
How to
- Add your PDF.
- Add black boxes over the information to remove.
- Start, then download the redacted PDF.
Frequently asked questions
Can the hidden text be recovered?
No. The affected pages are saved again as images with the black boxes: the original text no longer exists in the file. The other pages stay intact.
Are my files uploaded to a server?
No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.
Is there a file size or number limit?
No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.
Is it really free?
Yes. No sign-up, no watermark added to your documents and no usage limit.
