Document X-Ray Gives Files a Second, Machine-Readable View

Field notes

The scanner compares a document’s rendered pixels with its extracted text rather than relying only on suspicious phrases. The page lists detection for white runs, invisible rendering, zero-opacity fills, text under images, sub-4pt type, content outside the crop box, and Unicode tag characters. A displayed résumé sample contains six findings, with 46.1% of its text marked invisible; the page also states that files are deleted after scanning and offers offline installation.
