Image Guides
Images are usually the heaviest thing on a page, and the difference between a good format choice and a careless one is often measured in megabytes. These guides compare the formats that matter — JPEG, PNG, WebP, AVIF, GIF, SVG and HEIC — on the axes that actually decide the answer: compression efficiency at a given quality, transparency support, animation, encode time, and how many of your visitors' browsers can decode the result. There is detail on the things that quietly ruin quality, such as re-encoding a JPEG repeatedly, converting a photograph to PNG, or resizing before compressing rather than after. Practical workflow guides cover batch conversion, choosing a quality setting by inspecting the output rather than guessing, stripping metadata that leaks location data, and when a vector file is the correct answer to a raster problem.
