HEIC and SVG 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.
SVG is not a picture of an image — it is XML describing shapes, paths and text. Because it stores instructions rather than pixels, it renders perfectly at any size, from a favicon to a billboard.
- Where HEIC files come from
- Every iPhone photo taken since 2017, unless the camera format was changed to “Most Compatible”.
- Where SVG is used
- Design tools like Figma and Illustrator, and icon libraries.
