How it works

Decode Apple HEIC and HEIF photos and re-encode as a standard format your other tools and devices can read.

HEIC (High Efficiency Image Container) is the default photo format on recent iPhones. It's smaller than JPEG at the same quality but not supported by most non-Apple software. The tool uses libheif compiled to WebAssembly (via heic2any) to decode HEIC locally in your browser, then re-encodes as JPEG (most compatible), PNG (lossless), or WebP (modern, small). Quality slider (50 to 100, default 92) controls the lossy formats. Heads-up: HEIC is very compact, so the converted file is often larger than the original, that's not a bug, it's just JPEG being less efficient. Multi-image HEIC files (Live Photos, burst shots) return the first image. Output filename keeps the source name with the new extension.

How to use it

1. Drop your HEIC photo. iPhone HEIC and HEIF files are decoded locally by libheif compiled to WebAssembly.
2. Pick the output format. JPEG for maximum compatibility, PNG for lossless, WebP for smaller files.
3. Set the quality. The slider (50 to 100, default 92) controls the lossy formats.
4. Convert and download. The converted photo downloads — often larger than the HEIC, since HEIC is the more efficient codec.

Frequently asked questions

How do I convert HEIC to JPG without software?

Drop the HEIC file here. The decoder runs in your browser via libheif WASM, you don't need to install anything.

Why is the converted JPG bigger than the HEIC?

HEIC is a more efficient codec than JPEG, so converting up loses that efficiency. The image is visually identical, just larger on disk.

Does this work for iPhone Live Photos?

It decodes the still image inside the HEIC. The motion / video portion of a Live Photo isn't extracted by this tool.

Is my photo uploaded?

No. The decode and re-encode both happen in your browser.
