Why are iPhone photos in HEIC format?

Apple adopted HEIC (based on the HEIF standard) in iOS 11 because it produces files roughly 50% smaller than JPEG at the same visual quality. However, HEIC is not universally supported outside Apple's ecosystem.

Why does the conversion take a few seconds?

The heic2any library performs a full software decode of the HEIC container and re-encodes it as JPEG entirely in your browser. This is more CPU-intensive than a simple format swap and takes 2–10 seconds depending on file size and device speed.

What quality is the output JPG?

The output is encoded at 92% JPEG quality, which preserves near-lossless visual fidelity while producing a reasonably sized file.

Is my photo uploaded to a server?

No. The heic2any library is loaded into your browser and runs locally. Your photo never leaves your device.

About HEIC to JPG Converter

iPhones have shot photos in HEIC (High Efficiency Image Container) format by default since iOS 11. HEIC files are roughly half the size of equivalent JPGs, but the format is not supported by Windows Photo Viewer, most Android apps, many web platforms, or older image editors. This converter uses the heic2any JavaScript library — loaded on demand in your browser — to decode the HEIC/HEIF container and re-encode it as JPEG at 92% quality. The conversion can take a few seconds for large files because the library does the full decode-and-encode cycle client-side. A loading indicator shows while processing. If the file is not a valid HEIC/HEIF, an error message is shown. The output is a standard JPG you can open anywhere. No file is uploaded — the heic2any library runs entirely in your browser tab.
