- Squeezing the absolute most out of image performance budgets.
- Serving high-quality transparent graphics at tiny sizes.

PNG vs AVIF
PNG · Portable Network Graphics
PNG is a lossless raster format with full alpha transparency. It keeps text and sharp edges crisp, which makes it ideal for logos, icons, screenshots and UI graphics — at the cost of larger files for photographs.
AVIF · AV1 Image File Format
AVIF is built on the AV1 video codec and is one of the most efficient image formats available — often 50% smaller than JPG with better quality, plus transparency and HDR. Encoding is slower and support, while broad, is slightly newer than WebP.
