What is URL Encoding?

URL encoding, also known as percent-encoding, is a method to encode special characters in a URL. Characters that have special meaning in URLs (like &, =, ?) or non-ASCII characters must be encoded to be safely transmitted.

How URL Encoding Works

Special characters are replaced with a percent sign (%) followed by two hexadecimal digits representing the character's ASCII value:

  • Space becomes %20
  • & becomes %26
  • = becomes %3D
  • ? becomes %3F

Common Use Cases

  • Query Parameters: Encode values before adding them to URL query strings
  • API Development: Ensure special characters don't break API requests
  • Form Data: Encode form values for submission
  • Debugging: Decode URLs to see the actual values being sent

100% Private

This URL encoder/decoder runs entirely in your browser using JavaScript's built-inencodeURIComponent() and decodeURIComponent() functions. Your data is never sent to any server.
