How It Works

Encode or decode URLs by converting special characters to percent-encoded hexadecimal format.

URL encoding (percent-encoding) converts characters that are not allowed in a URL into a safe format. Reserved characters with special meaning in URLs, such as ?, /, #, :, and &, are replaced with a % followed by their two-digit hexadecimal ASCII code. Decoding reverses this process, restoring the original string. URL encoding is essential for including user input in query parameters and constructing valid web requests.
