reverse percent-encoding

How to use the url decoder tool

  • Paste the percent-encoded text into the input box.
  • The decoded, readable text generates automatically.
  • Copy the decoded result.

When you'd use this

Reading a URL parameter that's been percent-encoded.

Debugging a link that isn't behaving as expected due to encoding.

Frequently asked questions

What if the input isn't validly encoded?

Malformed percent-encoded sequences will cause a decoding error, which the tool will flag so you can check the input.
