Frequently Asked Questions
What is URL encoding?
URL encoding (also called percent encoding) converts special characters into a format that can be safely transmitted in URLs. Characters like spaces, &, and = are replaced with %XX codes.
When should I URL encode?
URL encode when passing data in query strings, form submissions, or API parameters. Any character that isn't a letter, number, or safe symbol (-_.~) should be encoded.
What's the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL but keeps characters like : / ? & intact. encodeURIComponent encodes everything except letters, numbers, and -_.~. Use encodeURIComponent for individual parameter values.
