URL encoding converts characters into a format that can be transmitted over the Internet. URLs can only be sent over the Internet using the ASCII character set, so URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.

💡 Pro Tip: Use the "Preserve URL-Safe Special Characters" option when you need to encode only certain parts of a URL while keeping its structure intact. This is particularly useful for encoding query parameter values without affecting the URL structure.
