Free URL Encoder/Decoder

What is this URL encoder/decoder?

A quick way to encode or decode URLs and query strings. Use encodeURIComponent for parameter values or path segments, and encodeURI for full URLs. Decoding reverses both modes. This is useful when building links, debugging redirects, and verifying webhooks. Everything runs locally in your browser.

How to use it

1. Paste text or a URL in the input.
2. Select the mode: encodeURIComponent (values) or encodeURI (full URL).
3. Click Encode or Decode to transform the text.
4. Copy the result and use it in your app or API calls.

Tips

• Use encodeURIComponent when encoding individual parameters.
• Use encodeURI for entire URLs so reserved characters like '/', ':' remain intact.
• If decoding fails, the input may be double‑encoded—decode more than once if needed.
