What is URL Encoding?

URL encoding (also called percent-encoding) converts characters into a format that can be transmitted over the Internet. URLs can only be sent using the ASCII character set, so special characters must be encoded.

Common Encodings:

  • Space → %20
  • ! → %21
  • # → %23
  • $ → %24
  • & → %26

Use Cases:

  • Passing parameters in URLs
  • Sharing links with special characters
  • API requests and responses
  • Form data submission
  • Email links with subjects
