Faqs

What is HTML encoding?

HTML encoding converts special characters to HTML entities (like < for <) to prevent them from being interpreted as HTML/JavaScript code, essential for security.

Encoding prevents XSS (Cross-Site Scripting) attacks when displaying user-generated content, ensures special characters display correctly, and allows showing HTML code as text.

Encoding converts text to HTML entities for security/display. Decoding converts HTML entities back to their original characters for readability/editing.

HTML entities are special codes that represent characters in HTML, like & for & or < for <. They ensure characters display correctly regardless of encoding.
