Secure HTML Entity Encoding & Decoding
The Kodivio HTML Encode & Decode tool is a mission-critical utility for web security and data presentation. Browsers interpret specific characters (like <, >, and &) as part of the HTML structure. To display these characters safely as text, you must convert them into their corresponding HTML entities.
