About the URL Decoder

Make encoded links readable again — tracking URLs, redirect parameters and API calls. After decoding, the tool parses the URL and shows each query parameter and value separately, which makes long marketing links easy to audit.

How to use it

  1. Paste the encoded URL or text.
  2. Read the decoded output.
  3. Review the parameter table for full URLs.

Good to know

  • Malformed sequences such as a lone % sign are reported rather than guessed.

Frequently asked questions

Why decode twice?

Some links are double-encoded; run “Reuse” on the output to decode again.

Is + a space?

In form-encoded query strings yes; untick the option for paths where + is literal.
