URL Encoder

Percent-encode special characters in a URL or query string.

About URL Encoder

URL Encoder percent-encodes text so it can travel safely inside a query string, path segment or form body. Spaces, ampersands and non-ASCII characters otherwise break the request.

Encoding follows encodeURIComponent semantics, which is what you want for individual parameter values.

How to use URL Encoder

  1. 1

    Paste the value

    Text, a query value, or a full URL you need to nest inside another parameter.

  2. 2

    Choose a mode

    Component mode encodes reserved characters; full-URL mode keeps ://?& intact.

  3. 3

    Copy the result

    Paste it into the request, redirect or tracking link.

Questions about URL Encoder

Space as %20 or +?

Use %20 in paths and modern query strings. + is only valid in application/x-www-form-urlencoded bodies.

Should I encode the whole URL?

No — that turns :// into %3A%2F%2F and breaks it. Encode individual values instead.

Why did my link break after adding &?

& separates parameters. Encode it as %26 inside a value.

Does it handle Unicode?

Yes, characters are UTF-8 encoded first, then percent-escaped.
