What is HTML encoding?

HTML encoding converts special characters into entity references so they display correctly in a web page. For example, < becomes < so the browser renders it as a less-than sign rather than interpreting it as a tag.

Which entities does the decoder support?

Named entities like &, <, >, ", , ©, ™, €, —, and more, plus decimal (<) and hexadecimal (<) numeric character references.

Does encoding happen on a server?

No. All encoding and decoding is done with JavaScript running locally in your browser. Your text is never transmitted anywhere.

When would I use HTML encoding?

Use it when you need to safely embed user-supplied text in HTML (to prevent XSS), when writing HTML source examples in documentation, or when debugging entity issues in a web page's source.
