How It Works
Enter any string in the input field. The encoder converts every character that is not safe in a URL — spaces, punctuation, Unicode — to its percent-encoded equivalent (e.g. space → %20). The decoder reverses the process, converting percent-encoded sequences back to readable text. Processing is instant and entirely client-side.
Use Cases
- Building query strings for API requests
- Debugging percent-encoded URLs in browser network tabs
- Encoding user-supplied values before appending them to URLs
- Decoding redirect targets or OAuth callback parameters
