Free URL Encoder & Decoder
Encode and decode URL components with Unicode support.
Uses component encoding. To encode a complete URL, process its query values separately. Decoding treats + literally, rather than as a form-encoded space.
Your files and input stay on your device. Their contents are not saved or sent to Analytics.
How to use the url encoder & decoder
Paste a query value or encoded component, choose Encode or Decode, then copy the output.
