HEIC to JPG Converter Online
Loading tool...
Apple switched iPhones to the HEIC (High-Efficiency Image Container) format years ago because it cuts file sizes in half. Unfortunately, Windows PCs, legacy CMS platforms, and many web APIs still outright reject HEIC uploads. This transcoder is built to convert Apple's proprietary format into a universally accepted JPG.
WebAssembly Decoding
Standard web browsers like Chrome and Edge do not natively know how to render a .heic file. To solve this without forcing you to upload your personal photos to a cloud server, this tool utilizes a WebAssembly (Wasm) decoder. It injects the HEIC decoding logic directly into your browser's memory, translates the complex container structure into a raw pixel array, and then repacks those pixels into a standard .jpg.
The File Size Penalty
HEIC uses advanced H.265 video compression algorithms applied to still images. Because standard JPG relies on older, less efficient compression mathematics, your converted file will almost certainly have a larger file size (often 2x larger) than your original iPhone photo.
Live Photo Extraction
If you upload an iOS "Live Photo," you aren't actually uploading a single image. A Live Photo is a HEIC file secretly bundled with a 3-second .mov video file. The WebAssembly decoder is programmed to ignore the video payload and only extract the primary high-resolution still image.
