Parse, edit, encode, and decode URL query strings and UTM parameters interactively.
Encode and decode URL query parameters and entire query strings. Break down complex URLs into an interactive key-value table, add or modify UTM tracking tags, and export properly encoded RFC 3986 URLs.
Unlike traditional web tools that send your personal data, uploaded photos, or sensitive text to remote cloud servers, our URL Query Encoder / Decoder operates strictly inside your client browser sandbox. This guarantees high processing speeds without network throttling, and ensures your data privacy is completely preserved.
