About CodeCogs

CodeCogs provides a LaTeX rendering engine that converts LaTeX markup into equation images for use on websites and mobile platforms. Equations are requested via a URL specifying an output format (PNG, GIF, SVG, EMF, or PDF) and a response type (image, JSON, JavaScript, or download), with the LaTeX markup passed as part of the URL. Rendered equations can be embedded directly as HTML image tags without requiring any installation.

The service supports additional formatting options within the LaTeX request, including font size presets, DPI settings for PNG and GIF output, and background/foreground color specification using hex codes or a set of named presets. A JSON output mode returns the rendered equation as a base64-encoded image along with metadata such as the cleaned equation text, output type, a unique cached file URL, and image dimensions for GIFs; cached equation images not reused within 48 hours are removed from the server.

The product is aimed at developers who need to display mathematical or scientific notation on web pages or in applications, offering integration guidance for tools such as CKEditor, TinyMCE, Blogger, and Angular, and covers usage via direct image embedding or through JSON/JavaScript-based retrieval methods like jQuery.
