Exchanging money should never require guesswork. This free currency converter uses the European Central Bank’s daily reference rates, served through the Frankfurter service, to convert between 30 major currencies — dollars, euros, pounds, yen, francs and more. Enter any amount, pick your pair, and you get the converted figure, the exact unit rate behind it, and the date that rate was published, all in one clear result card.
How the currency converter works
When the page loads, the tool downloads the full list of supported currencies from Frankfurter, so both menus always reflect what the service can actually convert. If that list cannot be reached, it falls back to twelve built-in major currencies and still works. When you press Convert, it sends your amount and pair to Frankfurter’s latest-rates endpoint. Frankfurter republishes the European Central Bank’s reference rates, so the answer is calculated from an official central-bank figure rather than from a commercial quote designed to sell you something. The result card shows the converted amount in large type, the unit rate (what one unit of the first currency buys), and the ECB publication date.
How to use it
Type the amount in the first box, choose the currency you have in From and the currency you want in To, then press Convert. The tool opens already showing 100 US dollars converted into euros, so you can see a worked example immediately. Use the swap button (⇌) to reverse the pair without re-selecting anything — handy for checking a price quoted to you in a foreign currency. Change any value and convert again; there is no limit and no account to create.
ECB reference rates, explained
The European Central Bank publishes reference rates once per working day, at around 16:00 CET, based on a concertation between central banks at 14:10 CET. They are an average snapshot intended for information, not a tradable price, and they cover the world’s most traded currencies against the euro. Frankfurter stores that daily series and does the cross-rate arithmetic for pairs that do not involve the euro: dollars to pounds, for example, is worked out through the euro. Because the rates update once a day rather than ticking every second, they suit budgeting, invoicing, price comparisons and travel planning far better than split-second trading decisions.
Mid-market rates versus bank rates
The rate shown here is close to the mid-market rate — the midpoint between what buyers and sellers offer on global markets, and the fairest benchmark available. Your bank, card network or bureau de change will almost never give you that rate. Instead they add a margin, often 1–4% for cards and high-street exchanges and sometimes much more at airports, plus fixed fees on top. That gap is where exchange providers make their money. Comparing the amount you are offered against the figure from this converter tells you exactly how much the transaction is costing you before you commit.
Travel money tips that actually save money
Check the reference rate before you travel so you know what a fair price looks like on the day. Pay in the local currency when a card terminal offers you a choice: choosing your home currency triggers dynamic currency conversion, which usually uses a noticeably worse rate. Avoid airport kiosks for anything beyond small emergency cash, withdraw larger sums less often to spread fixed ATM fees, and tell your bank about the trip so a legitimate foreign payment is not blocked as fraud.
Limitations worth knowing
ECB rates are published on working days only, so at weekends and on European holidays the converter shows the most recent working day’s rate — the result card always states that date. It covers around 30 currencies, not every currency in the world, and it excludes conversion fees, spreads and taxes entirely.
Rates are indicative only and not financial advice.
Currency Converter – frequently asked questions
How often are the rates updated?
Once per ECB working day. The date printed on every result card is the publication date of the rate used, so you always know how fresh the figure is.
Is the currency converter free?
Yes. It is completely free, works without sign-up, and you can run as many conversions as you like.
Why will my bank give me a different amount?
Because banks and exchange services add a margin and fees to the reference rate. This converter shows the benchmark; the difference is your provider’s charge.
Which currencies are supported?
Around 30 major currencies published by the ECB, including the US dollar, euro, British pound, Japanese yen, Swiss franc, and the Australian, Canadian and New Zealand dollars.
