Frequently Asked Questions

What's the difference between encodeURI and encodeURIComponent?

encodeURI preserves URL structure characters (:/?#[]@). encodeURIComponent encodes everything except alphanumerics and -_.!~*'(), making it ideal for query parameter values.

When should I URL-encode text?

Encode whenever user input, spaces, or special characters appear in URL paths or query strings. Without encoding, your URL may break or cause security issues like injection attacks.
