Frequently Asked Questions
Why do I need to encode HTML?
Characters like <, >, and & have special meaning in HTML. Encoding them as <, >, and & lets you display them as text and prevents them from breaking the page or enabling injection.
What is the difference between HTML encoding and URL encoding?
HTML encoding escapes characters for display inside HTML (<). URL encoding escapes characters for use in a web address (%20 for a space). They are different — use the URL encoder for links.
Does encoding protect against XSS?
Proper output encoding is a key defence against cross-site scripting, but it must be applied in the right context. This tool is a helper for understanding and testing encoding, not a full security layer.
