Images on the web

This post details the technical attributes of image formats, including compression algorithms (lossy vs. lossless), pixel density and resolution, bit depth, chroma subsampling (4:4:4, 4:2:2, 4:1:1, 4:4:0), progressive vs. baseline loading, alpha channels for transparency, and metadata/EXIF data. It also provides an overview of JPEG and PNG formats, discussing their compression methods, features, and use cases.
