HTML Entity Encoder & Decoder – Convert Special Characters Instantly

HTML Entity Encoder & Decoder – Free Online Tool

When working with HTML, some characters cannot be written directly because they are reserved by the browser. Characters like <, >, &, and " have a special meaning in HTML. If they are used directly, the code may break or display incorrectly. That’s why HTML entities are used. Our HTML Entity Encoder & Decoder tool helps you convert these characters safely and quickly.

What is HTML Entity Encoding?

HTML entity encoding is the process of replacing special characters with a safe code that browsers can read. For example, if you want to display a less-than sign, instead of writing the symbol directly, you should write <. This prevents confusion between real HTML code and display text. This method is essential for writing articles, tutorials, code snippets, or web applications without breaking the layout.

How Encoding Works – Simple Example

Normal Text: <div>Hello World</div>

Encoded Version: &lt;div&gt;Hello World&lt;/div&gt;

Using encoded format ensures the text appears as code, not as actual HTML content. This is essential when teaching HTML or sharing code online.

When Should You Use HTML Encoding?

• Writing tutorials with HTML examples
• Displaying code snippets on a blog
• Sending HTML via email safely
• Creating XML or JSON documents
• Preventing cross-site scripting (XSS) attacks

How Decoding Works

Sometimes content is already encoded, and you want to convert it back to normal. For example:

Encoded: &lt;p&gt;This is text&lt;/p&gt;

Decoded: <p>This is text</p>

Security Benefits – Protect Your Code

Encoding also plays an important role in security. Websites can be attacked using scripts inserted into user input. By encoding HTML characters, you prevent malicious code from being executed. This helps protect websites from XSS (Cross-Site Scripting) attacks.

Example of XSS Prevention

Input: <script>alert("Hacked")</script>

Encoded: &lt;script&gt;alert("Hacked")&lt;/script&gt;
