1. Your image stays local
EYECRYPT reads the selected image directly in your browser. The application is designed to inspect and rebuild files without uploading them to any server.
2. Metadata is inspected
The scanner checks available EXIF, GPS, XMP, IPTC, ICC, JFIF, camera, lens, timestamp, editing-software, authoring, copyright and image-container information.
3. Hidden-data indicators are screened
EYECRYPT looks for trailing bytes, common embedded file signatures, readable container text, unusual chunks and basic least-significant-bit pixel-distribution signals. These checks are heuristic and cannot prove the absence of steganography.
4. Purge rebuilds the file
Purge & Rebuild draws the browser-decoded image to an off-screen canvas and exports a brand-new PNG. This discards the original image wrapper and standard attached metadata such as EXIF, XMP, IPTC, comments and most container-level payloads.
Important limitation
A canvas rebuild preserves rendered pixel values. If someone embedded information directly into those pixels, a simple rebuild may preserve it. Use specialist forensic tooling for high-assurance steganalysis.
