Deep Technical Architecture & Forensic Specifications
Understanding how binary markers, byte endianness, and hidden secondary structures are decoded directly inside your V8 JavaScript / WASM environment.
TIFF IFD Structure & Binary Extraction
ToolAcre parses the JPEG 0xFFE1 App1 marker directly using local DataView pointers. It validates byte order (Little Endian II vs. Big Endian MM), traversing primary Image File Directory (IFD0), SubIFD offset pointers, and GPS SubIFD without serializing image bitmap memory.
Hidden Thumbnails & Inadvertent Leaks
Smartphones routinely generate secondary IFD1 thumbnails embedded inside headers. When a user crops or blacks out sensitive visual elements on a primary photo, the raw 160×120 thumbnail remains unedited inside the EXIF stream. Our sanitizer completely zeroes out secondary IFD1 allocations.
Social Network Stripping Caveats
While platforms like X (Twitter) and WhatsApp strip EXIF headers during ingress recompression, emailing original attachments, sending uncompressed files via AirDrop, or uploading to open cloud buckets keeps all high-precision GPS telemetry fully exposed to any recipient or downstream scraper.
