Frequently Asked Questions

What's the difference between encodeURI and encodeURIComponent?+

encodeURIComponent encodes more characters (including /, ?, &). This tool uses encodeURIComponent for maximum safety in query parameters.

Why are spaces encoded as %20?+

URLs cannot contain literal spaces. %20 is the percent-encoded representation of a space character.
