What is AVIF
The AVIF image format has several features and high compression rates. The continued expansion of the AVIF format is attributed to its support from big players in the digital economy. In addition to its high image quality, the AVIF format has many capabilities vital to modern image formats. The AVIF format currently reduces image sizes by about 50% compared to JPEG. As a result of its high efficiency, AVIF compression minimizes the loading time of websites. The AVIF standard has all the prerequisites necessary to establish itself online and replace JPEG as the new image standard of choice. Once technical obstacles (e.g., slow coding processes) have been overcome, the multifunctional image format will provide high-quality images.

Fastly AVIF support
Unfortunately to this date, Fastly does not support AVIF. It support WebP. It is uncertain whether this will change in future.
