FAQ
What's the difference between encodeURI and encodeURIComponent?
This tool uses encodeURIComponent, which encodes all special characters including / ? # &. Use it for encoding individual query parameter values, not full URLs.
Why are spaces encoded as %20?
RFC 3986 specifies %20 for spaces in URLs. Some forms use + instead, but %20 is the standard for URLs.
