HTML Entity Encoder Decoder

HTML entity encoding is the process of replacing special characters in HTML with their corresponding entity references. This prevents browsers from interpreting these characters as HTML markup and ensures your content displays correctly.

For example, the < character is encoded as &lt;, and the & character is encoded as &amp;. Without encoding, these characters would be interpreted as HTML tags or entity delimiters instead of literal text.

When Should You Use HTML Entity Encoding?

• Displaying code snippets in web pages (e.g., <div> instead of rendering a div)
• Showing special characters like &, <, > literally
• Preventing XSS (Cross-Site Scripting) attacks by sanitizing user input
• Including special characters in HTML attributes (e.g., title attributes)
• Ensuring valid HTML when using characters reserved for markup

1. Encode text — Type or paste HTML code into the left panel, then click Encode to convert special characters to HTML entities.
2. Decode text — Type or paste HTML entities into the right panel, then click Decode to convert them back to regular characters.
3. Copy the result — Use the copy button on each output field to grab the result for use in your project.
4. Clear individual fields — Use the Clear button on each panel to reset the input and output.

• Code display on blogs & tutorials — When showing HTML, CSS, or JavaScript code in web pages, encode the code to prevent the browser from executing it.
• XSS prevention — Always encode user-generated content before rendering it in HTML to prevent cross-site scripting attacks.
• Email templates — HTML emails require proper entity encoding to ensure special characters render correctly across email clients.
• XML/JSON data — Encode HTML entities within XML or JSON strings to maintain valid data structures.
• Debugging — Decode entity-encoded strings to inspect the original content when debugging web applications.
