About HTML Entity Encode Decode
HTML Entity Encode Decode converts characters such as ampersands, angle brackets, and quotes into entity references or decodes existing entities for inspection. Encoding is context-dependent; it does not sanitize untrusted HTML or make it safe to insert into a page.
Reference: HTML Living Standard: character references
01
How to use it
- Paste a small non-sensitive text or HTML fragment and identify whether it will be used in text, an attribute, a URL, JavaScript, or CSS.
- Encode or decode the value, then inspect the result for the exact target context.
- Use the destination framework's context-aware escaping and sanitization controls when rendering untrusted content.

Frequently asked questions
Do I need to encode every character in HTML?
No. Encode characters that have special meaning in the context where the value is placed, and let a trusted template system handle normal text output.
Does entity encoding prevent XSS?
Not on its own. Safe handling depends on the insertion context, proper escaping, sanitization where HTML is allowed, and security controls in the application.
Why did & appear instead of an ampersand?
& is the entity reference for an ampersand. It may display as & in rendered HTML, while source code keeps the encoded representation.
