When do I need to URL-encode text?

Whenever a value is placed inside a URL query string or path and contains characters like spaces, &, =, ?, or non-ASCII characters, which otherwise break the URL structure.

What's the difference between encodeURIComponent and encodeURI?

This tool uses component-style encoding, suitable for individual query parameter values. Full URLs (with :// and /) should not be encoded wholesale or they'll break.
