Sample HEIF File Download

HEIF uses HEVC (H.265) video compression to store still images at roughly half the file size of an equivalent-quality JPEG. It's a container format too, meaning a single HEIF file can hold multiple images, an image sequence, or a burst shot alongside its thumbnail.

Beyond compression, HEIF supports things JPEG never did natively — 16-bit color depth, depth maps for portrait-mode effects, and wider dynamic range — which is why phone cameras adopted it well before general web tooling caught up.

That tooling gap is the practical reason to test against a real HEIF file: support is inconsistent outside Apple's own ecosystem, so browsers, image libraries, and upload pipelines vary widely in whether they can decode one at all. Grab the sample below to check where your stack lands.
