FAQ

URL converter questions

What does encode do?

It turns reserved or non-ASCII characters into %HH sequences so the string can travel safely in a URL or query.

Does this use OpenAI?

No. Encoding and decoding are fixed algorithms that run in your browser. There is no AI step and nothing is sent to OpenAI for this tool.

Is my URL uploaded?

No. Conversion stays in your browser. Duyuz does not receive the string you paste into this tool.
