About String URL decoder
This tool URL-decodes a previously URL-encoded string. URL-decoding is the inverse operation of URL-encoding. All percent-encoded characters get decoded to characters that you can understand. Some of the most well known percent-encoded values are %20 for a space, %3a for a colon, %2f for a slash, and %3f for a question mark. The two digits following the percent sign are character's char code values in hex.
