How It Works

HTML escaping replaces "unsafe" characters with "HTML entities". This tells the browser to treat them as text content rather than code to be executed.

Common Developer Use Cases:

Displaying code snippets on a blog (so <div> shows up as text instead of creating a div).
Sanitizing user input before saving to a database or rendering.
Preventing Cross-Site Scripting (XSS) attacks.

Frequently Asked Questions

Why do I need to escape HTML?

If you display user input directly on a webpage, a malicious user could inject Javascript (XSS). Escaping converts special characters like < and > into safe text representations.

What characters are escaped?

The standard set includes: & (&), < (<), > (>), " ("), and ' (').
