What is URL encoding?
URL encoding (percent-encoding) converts reserved characters into a safe format so they can be used inside URLs and query parameters.
Use this tool to encode or decode URL strings instantly in your browser. Nothing is sent to the server.
How to use the URL Encoder
- Paste a URL or text into the Input field.
- Click Encode to apply percent-encoding.
- Click Decode to convert percent-encoded text back.
- Use Swap to switch Input and Output, or Copy to copy the result.
Tips
- For full URLs, encoding usually preserves characters like ":" "/" "?" "&" "=".
- For query parameter values, percent-encoding is typically stricter (it encodes more characters).
- If your input uses "+" for spaces, Decode will treat "+" as a space.
