About URL Encoding

What is URL Encoding?

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. URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.

Common Use Cases

  • Encoding URL parameters for API requests
  • Creating shareable links with complex parameters
  • Encoding form data before submission
  • Working with query strings containing special characters
  • Encoding URLs for use in email or social media

URL Encoding Examples

Space ( ) → %20
