About the HTML Encoder & Decoder
HTML encoding converts special characters like &, <, > and quotes into their safe entity equivalents so they display correctly in web pages without breaking markup. Decoding reverses this process. This free tool handles both directions in real time, entirely in your browser.

We believe developer and productivity tools should be accessible to everyone without paywalls.
Why do I need to encode HTML characters?
Characters like <, > and & have special meaning in HTML markup. Including them literally in content can break your page structure or cause security issues.
Encoding replaces them with safe entity sequences like <, > and & that browsers display as the correct character.
This is especially important when outputting user-generated content in HTML to prevent cross-site scripting vulnerabilities.
What is the difference between named and numeric entities?
Named entities use a descriptive name such as & for & or © for the copyright symbol.
Numeric entities use the character code directly, either decimal like © or hexadecimal like © for the same copyright symbol.
Both forms are valid HTML. The decoder here handles all three formats.
