How to use

Convert between HTML special characters and their entities.

Turn `<`, `>`, `&`, and quotes into `&lt;`, `&gt;`, `&amp;` and friends so text can sit safely inside HTML without being parsed as markup, or decode entities back into the original characters. Numeric forms such as `&#65;` and `&#x41;` are supported too.

Limits and privacy

Up to 200,000 characters. Numeric references outside the Unicode range are left as written.
