About HTML Encoding

HTML encoding is the process of converting characters that have special meaning in HTML (like <, >, &) into their corresponding HTML entities (e.g., &lt;, &gt;, &amp;).

This is crucial for security and proper rendering. For example, if you want to display the text "<p>This is a paragraph.</p>" literally on a webpage instead of having the browser render it as an actual HTML paragraph, you must encode it. This prevents unintended HTML from breaking your page layout and is a critical step in preventing Cross-Site Scripting (XSS) attacks when displaying user-generated content.

How to Use:

  • Encode: Select "Encode", paste your text (e.g., HTML code you want to display) into the input field, and the tool will convert special characters into their HTML entity equivalents.
  • Decode: Select "Decode", paste HTML entities (e.g., &lt;p&gt;) into the input, and the tool will convert them back into their original characters.
