Whether you are choosing between WebP and AVIF, deciding what quality setting to use for a JPEG, or trying to improve your site's Largest Contentful Paint score, the answers depend on understanding the underlying concepts. These guides walk through them clearly and practically.

Compression is how you trade image quality for smaller file sizes — but how that trade-off works differs significantly between lossy formats (JPEG, WebP, AVIF) and lossless formats (PNG). This guide explains what actually happens during compression and how to pick quality settings that work for your specific use case.
Each image format has a different set of strengths — different compression behavior, transparency support, animation support, and browser compatibility. This guide compares all the major formats so you can choose the right one without guessing.
