HTML Encoder / Decoder
Convert special characters to HTML entities and back. Important for web development and security.
How does this tool work?
This tool converts special characters into HTML entities to ensure correct display in web browsers.
Enter text with special characters (like <, >, &) to encode them safely for HTML code (e.g., <). Conversely, you can decode HTML-entitfied code to restore the readable text. This is essential for preventing XSS and for clean markup.
