What are HTML entities?

HTML entities are codes that represent special characters in HTML — characters that would otherwise be interpreted as HTML markup. For example, < becomes < and & becomes &.

How do I encode HTML entities?

Paste your text in the input area and click "Encode". Characters like , &, ", and ' are replaced with their HTML entity equivalents.

How do I decode HTML entities?

Paste text containing HTML entities and click "Decode". Entities like <, &, and " are converted back to their original characters.

Which characters are encoded?

The five characters with HTML significance are always encoded: & (ampersand), (greater than), " (double quote), and ' (apostrophe). Extended encoding covers all non-ASCII characters too.

Is this tool useful for preventing XSS?

Yes — encoding user-supplied content before inserting it into HTML prevents cross-site scripting (XSS) attacks by ensuring special characters cannot be interpreted as HTML or script tags.
