by•
A complete image format database covering 156 formats, with MIME types, extensions, magic bytes, browser support, technical specifications, developer code snippets, and format comparisons. It also includes a free JSON API and embeddable references, making the data useful both for developers looking up format information and for integrating it into their own projects.

I built this because working with image formats often means searching through different specifications, MIME registries, browser documentation, and code examples just to answer one simple question. So I put the information I kept looking for into one place. The database now covers 156 image formats, including MIME types, magic bytes, browser support, technical specifications, detection steps, and developer examples. I also added comparisons, a free JSON API, and embeddable references. It’s part of Free WebP to JPG’s expansion from image conversion into a broader set of image tools and developer resources. I’d love to know: what image-format information do you find yourself looking up most often?
