URL Encoder / Decoder
Percent-encode and decode URLs, paths and query values.
The converted URL will appear here.
About the URL Encoder / Decoder
URLs allow only a limited set of characters, so spaces, ampersands, accents and non-Latin scripts must be percent-encoded. This tool encodes and decodes those values, with a choice between encoding a full URL and encoding a single component.
That distinction matters. Encoding a whole URL preserves the separators such as slashes and question marks, while component encoding escapes them, which is what you need for a query parameter value.
