HTML Entity Encoder / Decoder

HTML Entity Encoder and Decoder handles the conversion between readable characters and their HTML entity representations in real time. The Encode tab takes any plain text and converts characters to HTML entities — essential for safely displaying user input in HTML and preventing XSS injection. The Decode tab reverses the process converting entity references back to their character equivalents. The searchable HTML entity reference table below the tool is a comprehensive resource covering 100 named entities with character, named entity form, numeric entity form, and description. Searchable by character, entity name, or description, it doubles as a quick reference during development.
