What is URL Encoding?
 
URL encoding (percent-encoding) converts special characters in a URL into a format that can be safely transmitted. Characters like spaces, ampersands (&), and non-ASCII symbols are replaced with % followed by their hexadecimal value.
 
What is it used for?
 
     
  • Query strings: Encode parameters in URLs (e.g. ?q=hello+world)
    •  
  • API requests: Safely pass special characters in GET parameters
    •  
  • Form data: Encode form values for URL submission
    •  
  • Links: Create valid URLs with special characters
    •  
 
How it works
 
Encode converts characters to %XX format (e.g. space → %20). Decode reverses this. All processing happens in your browser—no data is sent to any server.
