What is URL Encoding?
URL encoding (percent encoding) converts characters that are not allowed in a URL into a format that can be transmitted. For example, a space becomes %20 and & becomes %26.
When Do You Need URL Encoding?
- Passing query parameters with special characters
- Encoding form data for GET requests
- Sharing URLs with non-ASCII characters (e.g., Hindi, Chinese text)
- Debugging API requests with encoded parameters
