When do I need to URL-encode a string?
Whenever a value is placed inside a URL — a query parameter, path segment, or form submission — and might contain reserved characters like spaces, '&', '?', or '#' that would otherwise be misinterpreted as part of the URL's structure.
What's the difference between encodeURIComponent and encodeURI?
This tool uses encodeURIComponent, which escapes nearly everything except unreserved characters — correct for encoding a single query parameter or path segment. encodeURI (not used here) preserves characters like '/', ':', and '?' since it's meant for encoding a whole URL, not a component of one.
Does it handle emoji and non-ASCII characters?
Yes — non-ASCII characters are encoded as their UTF-8 byte sequence in percent-encoded form (e.g. an emoji becomes multiple %XX groups), matching how browsers actually encode URLs.
