About

HTML Entities encodes special characters — <, >, &, quotes, and hundreds more — into their HTML entity form and decodes them back, in named (&), numeric, or "encode everything" modes. It auto-detects which direction you need based on what you paste. Useful for safely embedding text inside HTML without breaking markup. Runs entirely in your browser.
