About PNG
Portable Network Graphics
A lossless raster format published in 1996 as a patent-free replacement for GIF. It compresses with DEFLATE and supports full alpha transparency. Use it for screenshots, logos and graphics with sharp edges or text, where JPG compression would leave visible artifacts.
About AVIF
AV1 Image File Format
An image format from the Alliance for Open Media, finalized in 2019, that stores AV1-compressed images in a HEIF container. It supports lossy and lossless compression, alpha and HDR, and its files are often smaller than WebP. Use it for web images when you want the smallest files; current Chrome, Firefox and Safari all display it.
