What Is HTML Encoding?

HTML encoding converts special characters into their corresponding HTML entities so they display correctly in a browser without being interpreted as HTML markup. For example, < becomes < and & becomes &.

Characters Encoded

Character	HTML Entity
&	&
<	&lt;
>	&gt;
"	&quot;
'	&#39;

How to Use

1. Paste or type your text in the input box.
2. The encoded result appears instantly in the output box (Auto mode on by default).
3. Copy the result or upload a text file for bulk encoding.
4. You can also pre-fill the input via URL: append ?input=your+text to the page URL and the tool will encode it automatically on load.

When to Use HTML Encoding

• Displaying user-submitted content safely in a web page
• Embedding code snippets inside HTML without breaking the markup
• Preventing XSS (Cross-Site Scripting) vulnerabilities
• Storing HTML content in XML or JSON attributes
