URL Parser & Encoder

Nothing leaves your browser

Take a URL apart, edit its query parameters and see the result in the URL, and see exactly how encodeURI, encodeURIComponent and form encoding differ.

Everything is worked out in this tab; nothing is sent anywhere.

Take a URL apart

Encode and decode

MethodEncodedCopy
encodeURIComponentOne piece of a URL: a query value, a path segment. Encodes everything that has a meaning in a URL.Type some text above.
encodeURIA whole URL. Keeps the punctuation that structures it (: / ? # & = @ and more) and encodes the rest.Type some text above.
Form (x-www-form-urlencoded)A form body or a query string written by a browser. A space becomes +, and more characters are encoded.Type some text above.

Use encodeURIComponent for one value, encodeURI for a whole URL that is already well-formed, and the form style for what a browser sends from an HTML form. Encoding text that is already encoded turns every % into %25.
