AVIF is an image file format that uses AV1 compression, offering better image quality and smaller file sizes compared to JPEG.
AVIF supports both still and animated images, high dynamic range (HDR) and standard dynamic range (SDR) content, and various color spaces and depths.
AVIF support has been integrated into popular browsers like Chrome and Firefox, as well as software applications and operating systems, but it is still not widely supported by all platforms and messaging apps.
