About this tool

Converts characters into their corresponding HTML entity codes, providing a comprehensive listing of both named and numeric entities. The tool displays special character representations alongside their raw ASCII equivalents, making it easy to look up how specific symbols are coded within web development languages. Users can input various characters or search the reference guide to find the exact syntax required for displaying symbols that have reserved meanings in HTML structure. Developers and web designers utilize this resource when they need to ensure that special characters—such as ampersands, less-than signs, or copyright symbols—render correctly within a webpage's code. It helps prevent display errors by allowing precise encoding of non-standard text elements.
