How to Use
Encode:

* Useful for including special characters in URL parameters or making API requests.

About this tool

The URL Encoder percent-encodes and decodes strings using standard URI rules. You can paste either a raw string or an already-encoded URL and convert between the two safely.

Common use cases

  • Build query strings that include spaces, plus signs, or non-ASCII characters.
  • Decode a long redirect or tracking URL to see where it really points.
  • Prepare parameters before sending them to an API or webhook.
  • Share complex URLs in chat or email without breaking special characters.
