This online URL Encoding/Decoding Tool allows you to convert content between its unencoded and encoded forms. This online tool is convenient when encoding a string to be used in a query part of a URL, as a convenient way to pass variables to the next page. URL encoding converts characters into a format that can be safely transmitted over the Internet. URLs can only be sent over the Internet using the ASCII character-set. Since URLs often contains characters outside the ASCII set, the URL has to be converted. URL encoding converts the URL into a valid ASCII format.

URLs should be encoded everywhere in an HTML document that a URL is referenced to import an object (A, APPLET, AREA, BASE, BGSOUND, BODY, EMBED, FORM, FRAME, IFRAME, ILAYER, IMG, ISINDEX, INPUT, LAYER, LINK, OBJECT, SCRIPT, SOUND, TABLE, TD, TH, and TR elements.)

What Is URL Encoding?
URL encoding stands for encoding certain characters in a URL by replacing them with one or more character triplets that consist of the percent character "%" followed by two hexadecimal digits. The two hexadecimal digits of the triplet(s) represent the numeric value of the replaced character.

Which Characters Are Allowed in a URL?
According to RFC 3986, the characters in a URL have to be taken from a defined set of unreserved and reserved ASCII characters. Any other characters are not allowed in a URL.
