Understanding URL Encoding

How URL Encoding Works

  • • Converts special characters to %XX format
  • • Uses UTF-8 encoding for Unicode characters
  • • Safe for HTTP URLs and query parameters
  • • Preserves alphanumeric characters and safe symbols
  • • RFC 3986 compliant encoding standard

Common Characters

Space → %20
& → %26
? → %3F
= → %3D
+ → %2B
% → %25
🌍 → %F0%9F%8C%8D

💡 Pro Tips

  • • Always encode URLs before sending them in HTTP requests
  • • Use encodeURIComponent() for query parameter values
  • • Use encodeURI() for complete URLs (preserves :// and /)
  • • Our tool uses encodeURIComponent() for maximum compatibility
  • • URL encoding is reversible - you can always decode back to original

What is URL Encoding?

URL encoding, also known as percent encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It converts characters into a format that can be transmitted over the Internet safely. Characters are converted to %XX format where XX is the hexadecimal representation of the character.
