How to use it?

Choose Encode or Decode, paste your text, then run the action. Use examples below to see common patterns.

About URL Encoding

URL encoding (percent-encoding) converts characters into a format that can be transmitted over the Internet. Special characters are replaced with a percent sign followed by two hexadecimal digits.

Common Encodings:
  • • Space → %20
  • • @ → %40
  • • & → %26
  • • ? → %3F
  • • = → %3D
  • • # → %23

Use Cases

Query Parameters

Encode values in URL query strings to handle special characters safely.

Form Data

Encode form data when submitting via GET requests or URL parameters.

API Requests

Properly encode parameters when making HTTP requests to APIs.

Debugging

Decode URLs to understand what data is being transmitted.
