HTML Encoder

This tool converts plain text into HTML-safe output by escaping characters like <, >, &, and quotes so they display correctly on web pages. Whether you’re pasting in raw HTML, injecting text into a script, or preparing code for tutorials, the tool gives you clean, encoded output that won’t break your markup. It works live as you type or import a file, and includes toggle options for quotes and Unicode handling.

What the HTML Encoder Tool can do:

It transforms any text into HTML-safe output by escaping the characters that browsers treat as code. You can choose whether to escape quotes for safer attribute usage, or fully encode Unicode symbols for maximum compatibility. It supports real-time updates, file imports, copy/export actions, and works entirely in your browser.

Example:

Input:

<div class="alert">5 < 10 & "ok"</div>

Output:

&lt;div class=&quot;alert&quot;&gt;5 &lt; 10 &amp; &quot;ok&quot;&lt;/div&gt;

Common Use Cases:

Use this tool when you’re embedding user-generated text into HTML, creating examples for a blog or tutorial, or protecting markup in emails or CMS content. It’s ideal for frontend developers, content creators, and anyone needing to sanitize text for the web. You’ll never have to manually replace characters again.

Useful Tools & Suggestions:

If you’re cleaning up or preparing content for web use, HTML Decoder helps you revert escaped characters back into readable text. And when you’re working with more specific formatting needs, Text to HTML Entities Converter offers precise control over converting symbols, punctuation, and special characters into HTML-safe code.
