Free HTML Encoder & Decoder
Encode and decode HTML entities to prevent XSS attacks
Our free HTML Encoder & Decoder tool helps you encode special characters in HTML for safe display on web pages, or decode encoded HTML back to its original format. Perfect for developers, security professionals, and anyone working with raw HTML.
🔗 What is HTML Encoding?
HTML encoding converts characters that have special meaning in HTML (like <, >, &, ") into their corresponding HTML entities (like <, >, &, "). This prevents the browser from interpreting them as HTML tags, which is crucial for preventing Cross-Site Scripting (XSS) attacks.
