Instantly convert text to URL-encoded format and vice versa.
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 often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format.
Decoding is used when you want to see the original content of an encoded URL. For example, it converts "%20" back to a space and "%21" back to an exclamation mark. This is useful for debugging and reading parameters in a URL.
