Compatibility

Formats we can describe honestly.

Metadata support depends on the file, browser, camera, and whether editing software preserved the original tags.

Initial interface support

• JPEG/JPG: primary supported format for common EXIF, IPTC, XMP, ICC, and GPS data.
• TIFF: supported for TIFF/EXIF metadata structures.
• DNG: accepted for initial testing; deep MakerNote results vary by camera.
• HEIC/HEIF and AVIF: accepted when the browser and file expose readable metadata.

Camera RAW formats under evaluation

NEF/NRW, CR2/CR3, ARW, RAF, ORF, RW2, PEF, and RWL are not yet advertised as supported. They require representative original files and real-device testing before model-specific claims are made.

Browser limitations

Large RAW files and deeper WebAssembly analysis can require significant memory. Mobile browsers may terminate an analysis even when the file itself is valid. The fast metadata pass remains available when deeper analysis cannot start.

Shutter count limitations

Shutter count is not a universal EXIF field. It may be absent, proprietary, encrypted, removed during editing, limited to mechanical captures, or available only through direct camera communication.
