DoxlyBlack out sensitive text so it genuinely cannot be recovered.
Most free redaction tools draw a black rectangle over the text and stop there. The words are still in the file underneath, and anyone can select them, copy them out, or run a text extractor and read every one. This has caused real leaks in court filings and government documents.
Doxly does the second half. It finds your terms using the document's text layer, covers them, and then flattens every page to an image, so the original characters are gone from the file rather than merely hidden. The trade-off is that the output is no longer searchable text.
No. Pages are rasterised to images, so the characters no longer exist in the file. That is the difference between this and a black box drawn over live text.
Flattening to images is what makes the removal permanent. Keeping the text selectable would mean keeping the text, which defeats the purpose.
Search matching needs a text layer. A scan is a picture of words, so there is nothing to search and nothing will be found. Redacting scans needs OCR, which Doxly does not do yet.
It removes the text you specified from the visible pages. Check the document properties separately if the author name or title also needs to go.
Always. Matching is literal — a name spelled differently, split across a line break, or written with an initial will not match. Read the output before you send it.
