Encoding

URL Encoder / Decoder

FAQ

What is the difference between encodeURI and encodeURIComponent?
encodeURI preserves URL syntax characters (such as / ? &) so it is safe for full URLs. encodeURIComponent escapes everything that is not a literal value, which is what you want for individual query parameters.
Why are spaces sometimes shown as %20 and sometimes as +?
Both are valid in different contexts. application/x-www-form-urlencoded uses +, while URL paths use %20. This tool defaults to %20.
