About HTML Encoder/Decoder

Web browsers interpret symbols like '<' and '>' as code tags, not text. To display these characters safely on a webpage (for example, in a tutorial), you must convert them into 'HTML Entities'. Our HTML Encoder/Decoder automates this process, ensuring your code snippets display correctly and formatted securely to prevent XSS attacks.
