HTML Entity Converter

Only &, <, >, ", and ' have reserved meaning in HTML markup itself (they open tags, close attributes, or start entities), so only they strictly need named entities to appear literally on a page. Every other character is encoded numerically here, which works identically in every browser and every HTML version, even for characters that don't have a widely-recognized name.

No, both represent the exact same character and render identically; &#233; and &#xE9; are the same é. Decimal is more common in hand-written HTML, hexadecimal is more common when the value comes from a programming context (since Unicode code points are usually written in hex, like U+00E9).

Yes. Rather than relying on a hand-maintained list, decoding is handled by your browser's own built-in HTML parser, the same one that renders every webpage you visit, so it correctly resolves all several thousand officially defined HTML5 named entities plus any numeric decimal or hexadecimal entity.

Yes. Decoding uses a detached, inert document created by the browser's DOMParser, which never executes scripts, loads images, or renders anything, it only reads the resulting text content back out.

Common cases include displaying user-submitted text safely inside an HTML page without it being interpreted as markup, embedding special characters or symbols in HTML/XML source, debugging a page that is showing literal &amp;amp; or &amp;lt; instead of the intended characters, or cleaning up entity-encoded text copied from a CMS or scraped webpage.
