URL Encoder / Decoder

Percent-encode or decode URLs, query values and form data, or break a URL into its parts.

In-browser · no upload

Runs entirely in your browser. Your files and text are not uploaded to our servers.

To URL-encode text, paste it, choose a mode and select Encode. Component encodes everything reserved (use it for query values); Full URL keeps : / ? & = so the URL still works; Form data writes spaces as +. Break down URL lists the protocol, host, path and each query parameter.

Frequently asked questions

What’s the difference between encodeURI and encodeURIComponent?

encodeURI (Full URL mode) keeps characters that structure a URL; encodeURIComponent (Component mode) encodes them too, which is correct for individual values.
