How the tools work

Each tool is a static web page. The conversion code is downloaded to your browser and runs there; we do not receive, store or see the files you open. No account is needed to use the free versions.

Paid plans: each tool shows a planned Pro tier with its price. Pro checkout is not open yet; nothing can be bought on this site today. When it opens, payments will be handled by our payment provider and the refund policy will apply.
