Questions people ask
Are my files uploaded?
No. This tool runs in your browser. Your file is read and processed on your device and never sent to our server.
Can redacted text be recovered?
No. The output has no text layer at all, only images with black boxes where the words were.
Does it find text in scans?
No. Scanned pages are pictures, so there's no text to search.
Do I need an account?
No. Every tool marked In your browser works without signing up, and there is no watermark on the result.
Does it work on a phone?
Yes, in any modern mobile browser. Very large files are easier to handle on a computer because phones have less memory.
