How it works

Three steps, no setup

Works on full URLs or individual query parameter values.

Uses encodeURIComponent under the hood for RFC 3986-compliant output.

Drop the encoded value straight into a query string or API call.

Common questions

Why are some characters left unescaped?

Reserved characters like / and : are only encoded when they appear inside a parameter value, not when they are structural parts of the URL itself.

What is the difference from encodeURI?

encodeURIComponent (used here) escapes more characters, making it the right choice for individual query values rather than whole URLs.
