HTML Entity Encoder / Decoder

What are HTML Entities?

HTML entities are special codes used to represent characters that have special meaning in HTML or characters that cannot be typed directly. An entity consists of an ampersand (&), a name or number, and a semicolon (;). For example, < represents <, & represents &, and   represents a non-breaking space.

Why Encode HTML Entities?

Certain characters like <, >, &, and " are reserved in HTML because they are part of the markup syntax. If you need to display these characters as text content, you must encode them as entities. Without encoding, the browser would interpret them as HTML tags or attributes, potentially breaking the page layout or creating security vulnerabilities like XSS (Cross-Site Scripting).

Common Use Cases

HTML entity encoding is used when displaying user-generated content safely, embedding code snippets in web pages, creating email templates, and preventing XSS attacks. This tool supports both named entities (© → ©) and numeric entities (© → ©).
