Which characters get encoded?

Characters with special meaning in HTML, such as , &, and ", are converted into entities.

Are numeric references decoded too?

Yes. Both named references (&) and numeric references (&) are decoded accurately using the browser's built-in parser.

Is the content I enter sent to a server?

No. It's processed entirely using browser DOM APIs.

What happens without entities?

A bare < can be parsed as a tag and break the layout — and printing raw user input can become an XSS hole.

Is different from a space?

Yes — a normal space may wrap or collapse, while always holds and never breaks the line.

🔣 HTML Entity Encoder/Decoder

Converts characters with special meaning in HTML into entities, or turns entities back into their original characters.

Input

Result

How to use

Enter text or HTML code.
Click "Encode" or "Decode".
Copy the result to use it.

🎯 Use Cases

Safely display symbols like < and > inside HTML code
Attach a code snippet to a forum post or wiki
Restore the original text from entity-escaped content

Example

Input

<div class="box">텍스트 & 기호</div>

Output

&lt;div class="box"&gt;텍스트 &amp; 기호&lt;/div&gt;

Clicking "Encode" converts the < > & characters into the < > & entities. Double quotes (") are left untouched because they carry no special meaning inside a text node.

Common HTML entities

Characters that have meaning in HTML must be escaped as entities so they are not parsed as markup.

Char	Entity	Why
`<`	`<`	Prevents parsing as a tag start
`>`	`>`	Prevents parsing as a tag end
`&`	`&`	The entity prefix itself — always escape first
`"`	`"`	Double quote inside attribute values
`'`	`'`	Single quote inside attribute values
space	` `	Non-breaking space — never collapses or wraps
