よくある質問

›How fresh are the exchange rates?

Rates refresh hourly from the European Central Bank reference rates via our edge cache.

›Which currencies are supported?

All major fiat currencies — USD, EUR, GBP, JPY, CHF, CAD, AUD and 30+ others. For crypto use our crypto converter.

›Is the currency converter free?

Yes — completely free, no signup, no ads. We don't track which currencies you convert.

›Can I link to a specific conversion?

Yes — the URL updates with ?from, ?to and ?amount so you can bookmark or share any conversion.

›Are these rates accurate enough for accounting?

They're ECB reference rates, the standard public benchmark. For audited accounting always verify against your bank's actual rate of the day.

›What about historical exchange rates?

We currently show live rates only. For historical data check the ECB website directly.
