About URL Encoding:

  • • URL Encoding converts special characters into a format that can be safely transmitted over the internet
  • • encodeURIComponent encodes all characters except: A-Z a-z 0-9 - _ . ! ~ * ' ( )
  • • encodeURI preserves URL structure characters like :/?#[]@
  • • Base64 encoding is useful for encoding binary data or complex strings
  • • Spaces are encoded as %20 (not + sign, which is a common misconception)
  • • URL encoding is essential for passing data in query strings and form submissions
