Encode or decode URLs and query strings online for free. Handle special characters safely. Fast and processed in your browser.

What is URL Encoding?

URL encoding (also called percent-encoding) replaces special characters with a % sign followed by their hexadecimal value. This is necessary because URLs can only contain certain characters from the ASCII character set. Spaces become %20, special characters like & become %26, etc.

When do you need URL encoding?

  • Passing special characters in query string parameters
  • Encoding non-ASCII characters in URLs
  • Building API requests with dynamic parameters
  • Encoding form data for HTTP requests
