Currency Converter
Convert between more than 30 world currencies using daily reference exchange rates published by the European Central Bank. Just enter an amount, pick a From and To currency, and get an instant conversion — no sign-up, no spreadsheet, and nothing you type ever leaves your browser except the currency codes needed to look up a rate. Traveling internationally or juggling calls across regions? The Timezone Converter can help you plan meetings and trips alongside your currency math. If you're thinking about returns on money held or invested in another currency, the Investment Return Calculator is a natural next stop. And if it's length, weight, or volume you need to convert instead of currency, try the Unit Converter.
Only the ~30 major currencies covered by the free ECB reference-rate feed are supported here (no cryptocurrencies).
About Exchange Rates
The number you see here is a reference (or "spot") exchange rate — the midpoint rate at which one currency is being traded for another on global markets at a given moment, without any markup added on top. Central banks like the European Central Bank publish a reference rate once each business day based on a daily concertation procedure with central banks across Europe, and that's the figure this tool displays.
What you actually pay when you exchange cash, use a credit card abroad, or make an international transfer is almost always a little different from the reference rate. Banks, card networks, and currency-exchange kiosks add their own spread (a small markup baked into the rate they give you) and sometimes a separate flat fee on top. That's normal and not a sign anything is wrong — it's simply how those businesses cover their costs and make money on the transaction. Use the rate here as an accurate baseline for comparison, not as the exact rate you'll be charged.
Exchange rates float — meaning they change continuously — because currencies are bought and sold on open markets in response to interest rates, inflation, trade flows, political events, and overall supply and demand. Since this tool relies on a free, once-per-business-day data feed rather than a live trading terminal, treat the numbers as a same-day reference point rather than a tick-by-tick market price.

Frequently Asked Questions
How often do the exchange rates update?
The European Central Bank publishes reference rates once per business day, typically around 16:00 CET. Rates are not updated on weekends or ECB holidays, so on those days you'll see the most recently published rate.
Is this real-time trading data?
No. This tool uses the free Frankfurter.dev API, which republishes the ECB's daily reference rates. It's a great, honest baseline for everyday conversions, but it is not a live feed of the kind used for currency trading, where prices can move by the second.
Why does my bank or credit card give me a different rate than shown here?
Banks, card networks, and exchange kiosks build a spread (markup) into the rate they offer, and sometimes charge a separate fee as well. That difference is expected — the rate shown here is the unmarked-up reference rate, useful as a comparison point rather than a guaranteed transaction rate.
Is my data uploaded anywhere?
No personal data is collected or transmitted. The amount you type is never sent anywhere — it's used only to do local math in your browser. The only thing sent over the network is the two currency codes you selected, used to build the request URL that fetches published exchange rates.
Which currencies are supported?
Around 30 major world currencies — the same set published by the European Central Bank's reference-rate feed, including USD, EUR, GBP, JPY, CAD, AUD, and other widely traded currencies. Cryptocurrencies and less common local currencies aren't included since they fall outside this free data source.
Can I use this for tax or accounting purposes?
This tool is intended for quick, informational reference only — it is not an audited or certified financial data source. For tax filings, financial statements, or other official accounting purposes, use the specific exchange rate your tax authority or auditor requires (which may be an official annual, monthly, or transaction-date rate that differs from the figure shown here).
