Frequently Asked Questions
What is the difference between URL encoding and component encoding?
URL encoding (encodeURI) preserves characters that are valid in a full URL like /, ?, and #. Component encoding (encodeURIComponent) encodes those too, making it safe for query string values.
Why are spaces encoded as %20 or +?
Both are valid. %20 is standard percent-encoding for spaces. The + sign is used in application/x-www-form-urlencoded format (HTML forms). This tool uses %20 (RFC 3986 standard).
