Frequently Asked Questions about converters
Quick answers before you start.
What free converters does Supreme Pro offer?
Supreme Pro has 71 free converters, including Unit Converter, Currency Converter and Time Zone Converter. Each one opens on its own page, so you can start straight away without installing anything.
Do I need to sign up to use these converters?
No. The converters work without an account or sign-up. Open a tool, add your input and download or copy the result.
Are my files and data uploaded to your servers?
Most tools run inside your browser, so what you add stays on your own device. Each tool page explains how it works, and our privacy policy has the details.
Do the converters work on phones and tablets?
Yes. They are built for current versions of Chrome, Edge, Firefox and Safari on Android, iOS, Windows and macOS. Very large files can be slow on older phones.
How do I find the right tool quickly?
Use the filter box at the top of this page, the search button in the header, or the menus at the top of every page. Related tools are also listed at the bottom of each tool page.
Is there a limit on how often I can use them?
We do not limit how many times you use a tool. Because the work happens in your browser, the practical limit is your device's memory, so try a smaller file if a page slows down.
How are the conversions calculated?
Each converter uses standard conversion factors and rounds the result for display, so tiny rounding differences are normal. If you need more precision for science or engineering work, check the decimals you need.
