URL Encoding


URL encoding is a method used to encode Uniform Resource Locator (URL). URL encoding is needed because URLs can only be sent using the ASCII character set. Since URLs often contain characters outside of ASCII set, URL encoding is used to convert these characters into a format that can be transmitted. URL encoding is also known as percent encoding.

Characters that are not allowed in a URL are replaced with a “%” symbol followed by two hexadecimal digits that represent the ASCII code of the character. Here are some examples of URL encoding:

  • A space is typically encoded as %20 or as a + symbol.
  • A slash (/) is encoded as %2F, a question mark (?) is encoded as %3F, and a colon (:) is encoded as %3A.
  • Reserved characters that have special meaning in URLs (such as :, /, ?, &, #, etc.) are also encoded if they are part of the data and not part of the URL syntax. For example, the ampersand (&) is encoded as %26.
