You can use Encode to make strings safe for HTML insertion, or Decode to convert entities back to human-readable text.

About HTML Encode / Decode

The HTML Encode / Decode tool converts special characters (like <, >, &, quotes) into their HTML entity equivalents, and can also reverse that process. This prevents markup from being interpreted by the browser when you want to display raw HTML or safely inject user-provided content into a page.

Example

Input: <div class=”note”>Hello & welcome!</div>
Encode: <div class="note">Hello & welcome!</div>
Decode: <div class=”note”>Hello & welcome!</div>

How to use

Paste your text or HTML into the Input box.
Choose Encode to convert characters to entities, or Decode to convert entities back.
Toggle Preserve line breaks if you want newlines converted to <br> when encoding.
Click Copy Output to copy the result to clipboard.

Who should use this?

Web developers, content editors, and CMS users who need to safely display HTML code in posts or to sanitize small snippets of user input before rendering. If you need to remove HTML entirely, try Strip HTML Tags.

Notes & best practices

This tool is a convenience for encoding/decoding. For high-security scenarios (user input on public sites), use server-side escaping and proper sanitization libraries rather than client-only transformations.
