StillReadable catches what your “redacted” files forgot to hide

Field notes

StillReadable processes files inside a browser Web Worker and presents recovered material alongside its hiding place and relevance. The listed checks range from text beneath redaction boxes and tracked changes to hidden Excel sheets, PowerPoint speaker notes, cropped image remnants, GPS coordinates, camera serial numbers, and template paths. The page also supplies specimen files and a network-panel test, claiming that a strict Content-Security-Policy prevents uploads and that scanning continues after Wi-Fi is disabled.
