HEIC vs JPG: why iPhone photos won’t open everywhere
HEIC is Apple’s efficient default since iOS 11 — better compression, worse compatibility. Convert locally with a native-decode fast path.
HEIC (High Efficiency Image Container) has been the iPhone default camera format since iOS 11 — it stores photos at a similar visual quality to JPEG in roughly half the file size. The tradeoff: plenty of older software, some Windows workflows, and most upload portals still only accept JPG or PNG.
Converting one photo is easy in Apple’s own share sheet. Converting a batch, or doing it from a browser without installing anything, is where most “free HEIC converter” sites ask you to upload your photos to their server first.
TryQuickImg’s HEIC to JPG converter decodes locally: on Safari and iOS, it uses the operating system’s own native decoder (fast — no library download); on Chrome, Firefox, and Edge, which have no built-in HEIC support, it falls back to a WebAssembly decoder running in a background worker, so the tab doesn’t freeze on larger batches. Either path, the photo never leaves your device.
