CodeCogs
CodeCogs runs a keyless image-rendering service that turns a LaTeX markup string embedded in the URL path into a rendered equation, historically used to drop math into forums, wikis, and emails via a plain <img> tag. It supports PNG, SVG, GIF, PDF, and EMF output, plus a JSON mode that returns the render as base64 alongside a hosted file URL.
