Convert iPhone HEIC and HEIF photos into JPG or PNG that open anywhere. Decoding runs entirely in your browser — your photos are never uploaded.
HEIC is the format iPhones use by default since iOS 11. It stores the same photo in roughly half the space of JPG, but many Windows apps, older software and web uploaders cannot read it — which is why converting is so often necessary.
No. The HEIC decoder is WebAssembly running inside your browser tab. Photos, including any location data they contain, never leave your device.
The decoder is about 1.5 MB and downloads on first use, then stays cached. Later conversions in the same session start immediately.
Yes — Settings → Camera → Formats → Most Compatible switches the camera to JPG. That trades some storage for compatibility everywhere.
A Live Photo HEIC can contain several frames; the still key frame is converted, which is the image you see in your photo library.
