Turn %20-style percent-encoding back into readable text, or encode a string safely for a URL query parameter — instant, entirely in your browser. Free, no account needed.
Paste an encoded URL or query string to read it, or type a value to encode it for use in a link. The tool uses encodeURIComponent semantics, which is what you want for query-parameter values (it escapes &, =, ? and /).
Base64 encoding/decoding is available on the same page. Nothing is uploaded.
A space. Percent-encoding writes any byte that is not allowed in a URL as % followed by its hex value.
In query strings both are accepted by most servers; %20 is the RFC 3986 form and always safe.
