Qik URL Decoder/Encoder is a very simple to use tool meant to either encode or decode a list of URLs. By clicking on the desired option whether to encode or decode a url, this form will instantly convert into the version you have chosen.
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. Since URLs normally contain characters that are not included in the ASCII set, the URL must be converted into a valid ASCII format. URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits. URLs cannot contain spaces. URL encoding normally replaces a space with a plus (+) sign or with %20.
