AVIF (AV1 Image File Format) is an open, royalty-free image format based on the AV1 video coding standard. It offers state-of-the-art compression, often outperforming JPEG, WebP, and even HEIC in terms of file size and quality. AVIF supports High Dynamic Range (HDR) and Wide Color Gamut (WCG), making it ideal for delivering high-quality images on the web. Sample AVIF files are used to test next-generation web image standards. Developers use them to verify browser support and rendering performance. They are also used to test image optimization pipelines to ensure that AVIF encoding is applied correctly and that color profiles are preserved during conversion.
