Type of format Image format, Lossless/lossy compression algorithm Image format
Introduction WebP is an image format employing both lossy and lossless compression. As a derivative of the VP8 video format, it is a sister project to the WebM multimedia container format. WebP-related software is released under a BSD license. AV1 Image File Format (AVIF) is an image file format specification for storing images or image sequences compressed with AV1 in the HEIF file format. It competes with HEIC which uses the same container format, built upon ISOBMFF, but HEVC for compression. Version 1.0.0 of the AVIF specification was finalized in February 2019.
Technical details Google has proposed using WebP for animated images as an alternative to the popular GIF format, citing the advantages of 24-bit color with transparency, combining frames with lossy and lossless compression in the same animation, and as well as support for seeking to specific frames. AVIF supports features like: High dynamic range; 8, 10, 12 bit color depth; Lossless compression and lossy compression; Monochrome (alpha/depth) or multi-components; Any color-space including: wide color gamut, ISO/IEC CICP and ICC profiles; 4:2:0, 4:2:2, 4:4:4 chroma subsampling; Film grain.
