HTML entities represent characters that have special meaning in HTML (like <, >, &) or characters outside the basic ASCII range. Encoding these ensures safe insertion into HTML documents. "Encode all" converts every character to its numeric entity (&#NNN;), useful for obfuscation or testing.
Text to HTML Entities Converter helps you transform special characters into safe web-ready codes. Paste your text and the encoder replaces HTML-significant characters (& < > ' ") with their entity equivalents, plus optionally encodes every non-ASCII character as a numeric entity for maximum compatibility. Choose 'minimal' to escape only the five HTML-significant characters, or 'all non-ASCII' to encode every character above U+007F.
The decoder recognises the five built-in named entities (& < > " ') plus the full HTML5 named-entity list, plus decimal (&) and hexadecimal (&) numeric references. This is the right way to defang user-supplied text before injecting it into HTML documents, preventing accidental layout breaks. For robust web development, this HTML decode online tool handles character references efficiently, making it easy to manage your character encoding requirements.
Named entities are more readable; numeric entities work even when the named entity isn't recognised. For HTML5 either works. For XML, only the five built-in named entities are universally safe - use numeric for everything else.
Encoding the five HTML-significant characters (& < > " ') prevents text from being interpreted as markup, which is the foundation of XSS prevention. But always use a templating engine that escapes by default - relying on a manual pass is risky.
Both represent the apostrophe ('). ' is HTML5 / XML; in HTML4 only ' (numeric) was guaranteed to work. Modern browsers accept both.
Yes - hexadecimal numeric character references with the &#x prefix are decoded correctly. 🎉 decodes to 🎉.
