About URL encoder & decoder
- What does URL encoder & decoder do?

- Who is it for?
- Writers checking length against a limit, researchers cleaning up lists, developers encoding values, and anyone comparing two versions of a document.
- Is it free?
- Yes. URL encoder & decoder is free with no account, no watermark on your output, no daily cap and no trial period. Because it runs on your own device it costs us nothing to run, which is why there is no catch.
