URL Encoder / Decoder
Encode or decode URLs, URI parameters, and special characters in real-time with instant conversion.
What is URL Encoding (Percent-Encoding)?
URL encoding converts characters into a format that can be transmitted over the Internet securely. Characters outside the standard ASCII set or reserved characters (such as ?, &, =, /, and spaces) are replaced with a % followed by two hexadecimal digits.
