How It Works

Enter an amount, pick two currencies and swap them with one tap. The rates are the European Central Bank's official daily reference rates, fetched from the free Frankfurter API directly by your browser and cached briefly so repeated conversions cost nothing. The rate date is always shown — the ECB publishes once per working day around 16:00 CET, so weekend and holiday conversions use Friday's fixing.

Most currency pairs aren't published directly against each other — the ECB fixes every listed currency against the euro only, not against every other currency pairwise. So converting, say, Turkish lira to Japanese yen actually happens in two silent steps: the lira amount is converted to euros first, then that euro figure is converted to yen, bridging through the euro as an intermediate currency (some data providers bridge through the US dollar instead). This cross-rate calculation is standard practice across virtually every currency converter and most bank systems — but it does mean a triangular round-trip (TRY→JPY→TRY) can land a fraction of a percent away from the starting amount, purely from rounding at each intermediate step, not from any error in the tool.

Because the ECB reference rate is official, published, and traceable to a fixed date, it also serves a role beyond casual travel math: many businesses and accountants use it (or an equivalent central-bank fixing) as the documented exchange rate for invoicing, customs declarations, or converting foreign revenue into a home-currency figure for bookkeeping — precisely because it's a neutral, publicly verifiable number rather than whatever a particular bank quoted that day. Currencies with higher volatility, like the Turkish lira has shown against the euro and dollar in recent years, can move several percent within a single week, which is exactly why the displayed fixing date matters — a rate from last Friday can already be stale for a currency swinging that fast, even though it was accurate the moment it was published.

What to Know

• These are reference rates, not transaction rates: they're the fair midpoint of the market — not the rate your bank or exchange office will actually give you. Real-world transactions add a spread, typically 1–4% at banks and more at airport kiosks. Use this converter to know the honest baseline, then judge any offer against it.
• Publication schedule: the ECB fixes once per working day, around 16:00 Central European Time — intraday market moves after that point aren't reflected until the next fixing, and weekends/holidays simply carry the last working day's numbers forward.
• Cross-rate rounding: because most pairs are calculated through a bridge currency, expect tiny (sub-0.1%) discrepancies in round-trip conversions — this is a rounding artifact of the bridging method, not a data error.
• Coverage: around 30 major currencies the ECB tracks daily; it does not include cryptocurrencies or most emerging-market currencies the ECB doesn't publish.
• Privacy: your browser talks to the Frankfurter API directly; nothing you type is sent to this site's own server.
