HTML Entity Encoder/Decoder - Protect Web Content Code Blocks

About this Utility

The HTML Entity Encoder/Decoder is a lightweight text processing utility designed to safeguard web structures by translating special characters and tags into secure HTML Entities.

Publishing raw snippets (like code examples or special currency symbols) inside a CMS or web page can result in broken layout rendering or security issues. Converting symbols into safe named entities (like < or >) ensures that web browsers display your code correctly without executing it.

How to Use Step-by-Step

  1. Enter Raw Text: Paste your text, code snippets, or non-ASCII characters inside the input panel.
  2. Choose Mode: Switch between Encoding (for formatting) or Decoding (for reading raw strings).
  3. Select Options: Choose between Named, Decimal, or Hexadecimal notations, and specify character ranges.
  4. Retrieve Code: Copy the sanitized results instantly for your blogs, forums, or document editors.

Frequently Asked Questions

💡 What is the difference between Named and Hexadecimal entities?

Named entities use human-friendly labels (like <), whereas hexadecimal or decimal configurations use numerical Unicode sequences (like <). Hex/Dec covers all characters, while Named is optimized for readability of common symbols.

🛡️ Does encoding help prevent cross-site scripting (XSS)?

Yes, escaping user input by converting characters like <, >, and & into entities is a key practice to prevent browsers from parsing unauthorized scripts.
