Reads a HEIC/HEIF file (the default photo format on modern iPhones) or an AVIF image — both share the same underlying container format — and shows its brand, dimensions, and item details.
Checking a HEIC photo's dimensions and format details on a device or browser that can't display HEIC/AVIF natively.
Drop a .heic, .heif, or .avif file. Brand and dimensions appear immediately.
Reads the container's metadata boxes only — it does not decode the actual HEVC/AV1 image data, so no visual preview is shown.
