About this HTML Entity Encoder

The HTML Entity Encoder Decoder is a free online tool for encoding special HTML characters into their corresponding entity references and decoding entities back to plain text. HTML encoding is an essential security practice that prevents cross-site scripting (XSS) attacks by converting characters like <, >, and & into safe entity codes like &lt;, &gt;, and &amp;. This HTML encoder helps developers sanitize user input, display code snippets, and ensure proper rendering of special characters in web pages.

How to use the HTML Entity Encoder

  1. 1 Enter the text or HTML you want to encode or decode into the Input field.
  2. 2 Select "Encode HTML Entities" to convert special characters to entity codes, or "Decode HTML Entities" to convert entities back to characters.
  3. 3 Click the Run button to process your input.
  4. 4 Copy the encoded or decoded result from the output area for use in your HTML code.

Frequently Asked Questions

What are HTML entities?
HTML entities are special codes that represent reserved characters in HTML. For example, &lt; represents the less-than sign (<) and &amp; represents the ampersand (&). They prevent browsers from interpreting these characters as HTML code.
Why is HTML encoding important for security?
HTML encoding prevents cross-site scripting (XSS) attacks by converting user-supplied content so that it is displayed as text rather than executed as code. If you display user comments or dynamic content without encoding, malicious scripts can be injected into your web pages.
Which characters does this tool encode?
This tool encodes five essential HTML characters: & (ampersand), < (less than), > (greater than), " (double quote), and ' (single quote). These cover the most common XSS vectors and HTML syntax characters.
Can I use this to display code snippets on my website?
Yes, this tool is perfect for preparing code snippets for display on websites and blogs. Encode your code with the HTML entity encoder, then paste the result into your HTML. It will display exactly as written without being executed by the browser.
