Encoding one URL component

This tool applies encodeURIComponent to text. Spaces become %20 and reserved separators such as & are escaped.

Output behavior and limits

It encodes a component, not an entire navigable URL. Encoding a full URL also escapes its colon and slashes.

Encode 'red & blue' as red%20%26%20blue when placing it inside one query parameter; add the surrounding URL separately.
