Quick Answer

It converts HTML-special characters (&, <, >, quotes) into their named or numeric entities so they display safely in HTML without breaking the markup.

What Is HTML Entity Encoder / Decoder?

HTML Entity Encoder / Decoder is a free online developer tools tool that encode special characters to html entities or decode them back. An HTML entity encoder converts special characters that have meaning in HTML into their corresponding named or numeric entities. Characters like <, >, &, and quotes are part of HTML syntax, so if you include them in content without encoding, they can break the markup or cause rendering issues. For example, < becomes < and & becomes &. Encoding is essential when you want to display code snippets, mathematical expressions, or special symbols inside an HTML page without the browser interpreting them as tags. The decode direction reverses the process, turning < back into <. The tool supports both named entities (like ©) and numeric entities (like ©). All processing is client-side with no upload. Unlike many similar tools, it runs entirely in your browser — no data is sent to any server, no account is required, and there are no usage limits. Whether you are a developer, writer, SEO professional, or casual user, this tool provides instant, accurate results without friction.

When should I encode HTML entities?

Whenever you type or insert text that contains characters like < or & inside an HTML document and you want them to appear literally rather than be parsed as code.

Frequently Asked Questions

Find answers to common questions about this tool.

Why does my HTML show & instead of &?

Double encoding often causes this. If the text was already encoded once and you encode it again, & becomes &amp;. Decode first then re-encode to fix it.

Do I need to encode every special character in HTML?

Only the four core characters: < > & and ". In attribute values, also encode single quotes. Other characters like copyright symbols can be encoded but are not required.

What is the difference between < and <?

Both represent <. < is a named entity (easier to remember). < is a numeric entity using the ASCII code point. Both render identically in browsers.

How do I encode emoji in HTML?

Emoji can be represented as numeric entities using their Unicode code point. For example, the smiley face (U+1F600) becomes 😀 in HTML.

Does the tool handle encoding for XML or XHTML?

Yes. HTML entity encoding works for XML and XHTML as well. The same characters that need encoding in HTML also need encoding in XML.
