Frequently asked questions
Short answers to common questions about url encoder / decoder.
Why do URLs need encoding?+
URLs can only send ASCII characters. Special characters like spaces, "&", or "?" have special meanings and must be escaped to be treated as data.
What is the difference between encodeURI and encodeURIComponent?+
encodeURIComponent encodes characters like "&", "+", and "=" which usually separate query parameters, making it safer for encoding values.
