Currency Converter

Convert between 40+ currencies offline with built-in rates you can edit by hand — or refresh live when you're online. It all runs on your device.

Works fully offline with built-in rates — nothing is sent anywhere unless you press “Update rates online”, which fetches public exchange rates and keeps no personal data.

Quick conversions from USD

Reference

Built to work without a connection

Exchange rates move constantly, so the figures here ship as a sensible approximate baseline (USD-based) that you can override for any pair — handy for a quick estimate, a travel budget, or a quote on a plane. Every conversion is a cross-rate through the US dollar, computed in your browser. Online refresh is optional; the tool never depends on it.
