ℹ️ About HTML Encoding

What is HTML Encoding?

HTML encoding replaces reserved characters with HTML entities so browsers render them as literal text instead of HTML markup. Essential for safely displaying user-generated content.

Why Use It?

🔒 XSS Prevention — stops script injection attacks

📄 Display HTML as text — show code examples in pages

🔌 XML/RSS feeds — safely embed HTML in XML

📧 Email templates — ensure proper rendering

Encode vs Decode

Encode turns raw characters like < into entities like < for safe HTML embedding.

Decode is the reverse — converts entities back into the characters they represent.
