Quick Reference

Component mode uses encodeURIComponent / decodeURIComponent — encodes everything except A-Z a-z 0-9 - _ . ~ ! * ' ( ). Best for query parameter values and path segments.

Full URI mode uses encodeURI / decodeURI — preserves URL structure characters like : / ? # [ ] @ ! $ & ' ( ) * + , ; =. Best for encoding an entire URL while keeping its structure intact.
