Our tools are 100% accurate for standard number system conversions. We use proven mathematical algorithms and thoroughly test all conversions. For very large numbers, results are limited by JavaScript's number precision, but this is clearly indicated in the interface.

Absolutely! All conversions happen locally in your browser using JavaScript. Your numbers and conversion results never leave your device or get sent to any server. We don't collect, store, or track any personal information or conversion data.

Yes! Once you load any of our tool pages, they work completely offline. The initial page load requires an internet connection to fetch the HTML, CSS, and JavaScript files, but after that, all functionality works without any internet connection.

Yes, most of our tools support fractional numbers. For example, our binary-decimal converter handles numbers like 101.101₂, and our custom base converter works with fractional numbers in any base. Support varies by tool, but it's clearly indicated in each tool's interface.

We're currently evaluating embedding options. If you're interested in embedding our tools on your educational website or learning platform, please contact us with details about your use case and audience. We're generally open to collaboration with educational projects.

We don't currently offer a public API, but we're considering it for the future. Our focus right now is on providing the best possible user experience through our web interface. If you have specific API needs, let us know and we'll consider your requirements.
