Convert iPhone HEIC photos to JPG for free in your browser. HEIC is Apple’s default camera format and is rejected by most Windows software, upload forms and older applications — JPG opens everywhere.
Since iOS 11, iPhones have saved photographs as HEIC — a container using the HEVC video codec, which stores an image at roughly half the size of an equivalent JPEG with no visible quality loss. It is genuinely the better format. It is also encumbered by an expensive patent pool, which is why support outside Apple's ecosystem is still thin.
The practical result: Windows needs paid codec extensions, Chrome and Firefox will not display it, and essentially no government or exam portal accepts it.
If you are converting constantly, change the setting instead: Settings → Camera → Formats → Most Compatible. New photos will be JPEG. Also check Settings → Photos → Transfer to Mac or PC → Automatic, which converts on transfer. The trade-off is roughly double the storage per photo.
Everything runs locally — your photographs are decoded by a WebAssembly module inside your browser and never uploaded. That matters more than usual here, since a camera roll is about as personal as files get. Full background in the HEIC guide.
Windows needs the HEIF Image Extensions plus a HEVC codec extension, and the latter is a paid add-on most machines do not have. Converting to JPG sidesteps the problem entirely.
Yes, usually about twice the size. HEIC is simply a more efficient format. If size matters for an upload, compress the JPG afterwards.
The motion is discarded and you keep the still key frame. JPEG has no way to store the video component.
Yes — drop in as many HEIC files as you like and download the results as a ZIP. Conversion happens on your device, so there is no upload wait.
