About HTML Entities
What are HTML Entities?
HTML entities are special codes that represent characters which have meaning in HTML syntax (like <, >, &, quotes). They prevent browsers from interpreting these characters as HTML tags or attributes. Essential for XSS prevention and displaying special characters on web pages.
How to Encode HTML Entities
Paste text containing special characters, click Encode, and get the HTML-safe version with entities like &, <, >, ". Decode mode converts entities back to their original characters.
Why Encode HTML Entities?
The main reason is security — XSS (Cross-Site Scripting) attacks inject malicious HTML/JavaScript through user input. Encoding entities like < and > prevents the browser from executing injected code. Always encode user-generated content before displaying it in HTML.
