FAQ
Why do URLs need encoding?
Spaces, non-Latin characters and symbols like ?, & and = can be misread by browsers or servers. URL encoding converts them to safe %XX form.
encodeURI vs encodeURIComponent?
encodeURIComponent also encodes ?, &, = and /, making it right for a single parameter value. This tool uses encodeURIComponent, the most common choice for query parameters.
Does it support Unicode?
Yes, it uses UTF-8 so non-Latin characters encode and decode correctly.
