About this tool
Free URL encoder and decoder. Percent-encode or decode URLs, query strings and path segments using the correct URI component rules.
Frequently asked questions
Which encoding is used?
It uses encodeURIComponent semantics, which is correct for individual query values and path segments.
Why is a space %20 and not +?
%20 is the correct encoding for a URI component; + is only a convention inside application/x-www-form-urlencoded bodies.
Can it decode double-encoded values?
Run the decode step twice if you suspect the value was encoded more than once.
