About URL Encoding

What is URL Encoding?

URL encoding (also known as percent-encoding) converts special characters in URLs into a format that is safe for web transmission. Characters are represented with % followed by their hexadecimal code.

Common encoded characters:

espacio%20
!%21
#%23
$%24
&%26
+%2B
=%3D
?%3F

Common use cases:

  • Query parameters in URLs with spaces or special characters
  • Web forms that send data via GET
  • REST APIs with parameters in the URL
  • Redirects with URLs as parameters
  • Dynamic link building

Best practices:

  • Always encode URL parameters that contain user data
  • Don't encode the whole URL, only the necessary parameters
  • Use the language's native functions (encodeURIComponent in JS)
  • Decode URLs before showing them to the user for better readability
