URL Encoder / Decoder

urlencodedecodepercent encodingquerystring

Updated Mar 6, 2026

Encode and decode URL strings with full control over how they're handled. Switch between URL Component mode (for individual values, query params, and path segments) and Full URL mode (preserves scheme, host, and port while encoding path and query).

Includes an optional form-encoding toggle that treats '+' as a space (application/x-www-form-urlencoded), auto-detection, and copy-to-clipboard. Everything runs client-side — nothing is sent to a server.

Mode

Encodes/decodes a single value or parameter using encodeURIComponent. Use this for query values, form fields, or path segments.
