About this tool

Encode or decode URLs and components entirely in your browser. Choose encodeURIComponent when encoding a single parameter value or key, and encodeURI for full URLs (keeps :/?#[]@!$&'()*+,;= intact). Toggle whether spaces use + in query strings. The Query Helper lets you import a URL, edit key–value pairs, and rebuild a clean link. No data is uploaded.
