SVG and AVIF explained
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.
AVIF stores still images using the AV1 video codec's intra-frame compression. It generally achieves the smallest files of any widely supported format, and it handles wide colour gamut and HDR, which JPEG cannot.
- Where SVG files come from
- Design tools like Figma and Illustrator, and icon libraries.
- Where AVIF is used
- Performance-focused websites and modern image pipelines.
