How It Works

URL Encoding (Percent-encoding) converts characters into a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.

Frequently Asked Questions

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.
