What are HTML entities?

HTML entities are special codes used to represent reserved characters in HTML. For example, < is represented as < and & is represented as &.

Why should I encode HTML entities?

Encoding prevents the browser from interpreting special characters as HTML tags or attributes, which helps avoid rendering issues and cross-site scripting (XSS) vulnerabilities.

Which characters does this tool encode?

The encoder converts the five key HTML-reserved characters: & (ampersand), (greater-than), " (double quote), and ' (single quote/apostrophe).
