HEIC and WebP explained
HEIC is the container Apple uses for photos taken on iPhone since iOS 11, holding images compressed with HEVC. It stores roughly the same visual quality as JPEG in about half the space, and can hold extras such as depth maps and Live Photo frames.
WebP is a Google-developed format that offers both lossy and lossless modes, transparency, and animation in one container. In its lossy mode it typically produces files around 25–35% smaller than JPEG at comparable visual quality.
- Where HEIC files come from
- Every iPhone photo taken since 2017, unless the camera format was changed to “Most Compatible”.
- Where WebP is used
- Modern websites, and increasingly the default export from web-focused design tools.
