PNG vs AVIF:
Name PNG AVIF
Full name Portable Network Graphics AV1 Image File Format
File extension .png .avif
MIME image/png image/avif
Developed by PNG Development Group Alliance for Open Media
Type of format Lossless bitmap image format Image format
Introduction Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the Internet. PNG itself does not support animation at all. MNG is an extension to PNG that does; it was designed by members of the PNG Group. 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 PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB[A] images (with or without alpha channel). PNG was designed for transferring images on the Internet, not for professional-quality print graphics, and therefore does not support non-RGB color spaces such as CMYK. 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.
