How does Timezone Converter work without uploading my data?

Timezone Converter runs entirely inside your browser's sandbox: the page loads once, and every operation after that executes on your own device's CPU. No input, file, or result is transmitted to any server — you can even watch the network tab stay silent while you use it.

Does Timezone Converter cost anything or require an account?

No. Timezone Converter is completely free with no usage caps, subscriptions, or sign-up forms — supported by unobtrusive ads, and usable for personal and commercial work alike.

Can I use Timezone Converter on a phone or offline?

Yes. The layout adapts to phones and tablets, and because the logic ships as static client-side code, Timezone Converter keeps working on intermittent connections once the page has loaded.
