How to use this tool
Choose a direction and provide the string. Encoding handles ampersands, angle brackets and quotes; decoding supports selected names and numeric references rather than the complete HTML entity catalogue.
Results and examples
Encoding <b> produces <b> so the tag can be represented as text. Encoding < again gives &lt;, which is why the number of escaping passes matters.
Limitations
- The decoder does not implement every named HTML character reference.
- Character replacement is not universal protection for attribute, URL and script contexts.
