Redact text
Blacks out names, numbers or other data and removes them from the file: the redacted text cannot be recovered.
How it works
- Choose the files or drag them onto the page.
- Adjust the options (text to redact, quality of redacted pages) if you need to, then click “Redact text”.
- Download the result. Nothing left your computer.
This tool runs entirely in your browser: the PDF never leaves your device, and it works even without an internet connection.
Frequently asked questions
Can redacted text be recovered?
No. Pages with matches are rebuilt as images with the black box already applied: the original text no longer exists in the file, unlike a box simply drawn on top.
Is it safe to use “Redact text” with confidential documents?
Yes. The file is opened and processed by your own browser; it is not uploaded to any server, so nobody else has access to it.
Is “Redact text” free? Are there limits?
It is free, with no sign-up, no watermarks and no limit on uses per hour or per day. The only limit is your device's memory: files of hundreds of megabytes can be slow on a phone.
Does it work on a phone and without internet?
It works in any recent browser, on a computer, tablet or phone. After your first visit the site is saved and the tools work even offline.
What happens to my files afterwards?
Nothing is stored: when you close or reload the page, the files leave the browser's memory. The result exists only in the file you download.
