What is HTML Encode?
HTML encoding (also called HTML entity encoding) converts special characters into their HTML entity equivalents to prevent them from being interpreted as HTML markup. This is crucial for displaying user input safely and preventing XSS (Cross-Site Scripting) attacks in web applications.
How to Use HTML Encode
1. Enter or paste your text into the input field. 2. The HTML encoded result appears instantly in the output field. 3. Click "Copy" to copy the encoded text to your clipboard. 4. Use "Clear" to reset and start over.
When to Use HTML Encode
Use HTML encoding to safely display user-generated content on web pages, prevent XSS attacks, or show code examples in HTML. Always encode user input before displaying it!
How HTML Encode Works
Special characters like <, >, &, ", ' are converted to named entities (<, >, &, ", ') or numeric entities (<, >, etc.). This ensures they display as literal characters rather than being parsed as HTML tags or attributes by the browser.
Common Use Cases
- Preventing XSS attacks
- Displaying code in HTML
- Safely showing user-generated content
- Embedding special characters in HTML
- Form data sanitization
- Content Security Policy compliance
Security Note
🔒 Always HTML-encode user input before displaying it on web pages to prevent XSS attacks!
