Currency Converter

Exchange rates change every day, and published static charts are outdated the moment they are printed. This converter fetches live rates directly from the Frankfurter open-source API, so the rate you see is what the market set today — not last week. Rates are sourced from the European Central Bank reference rates, which cover the major global currencies.

Travelers estimating how much local cash to carry, online shoppers comparing prices in foreign storefronts, freelancers invoicing international clients, and anyone receiving a wire transfer in a foreign currency all need a current rate rather than a memorized approximation. The searchable currency menus let you find any currency quickly by code (USD, EUR, LKR) or name, and the swap button reverses the direction in one click. If the network is unavailable, the converter shows a clear error rather than silently displaying a stale rate.

Because live rates are retrieved from Frankfurter's servers, your selected currency code leaves your browser in the API request. No personal data is transmitted — only the currency code you choose. The converter discloses this openly so you know exactly what data is and is not sent.

Conversion uses live reference rates fetched from Frankfurter, which publishes the European Central Bank's daily rates. That is a genuine external request: the currency pair you select is sent to retrieve a rate, though the amount you are converting is not — the arithmetic happens locally once the rate arrives.

ECB reference rates are published once each working day, at around 16:00 Central European Time. They are a reference, not a traded price, and there are no updates at weekends or on ECB holidays — so a rate seen on a Sunday is Friday's.

Conversion between two non-euro currencies is derived through the euro, since that is the base the reference rates are quoted against.

A reference rate is the midpoint between buying and selling, and nobody trades at the midpoint. Every provider takes a spread, and it is frequently the largest part of what a transfer costs — often larger than any stated fee. A bank might apply two to four percent to a retail exchange, a card issuer rather less, a specialist transfer service less again.

That makes the mid-market rate the right benchmark rather than an expectation. Comparing what you were actually charged against it reveals the true cost of a transaction, which is exactly what providers quoting "no fees" while widening the spread are relying on you not doing.

Two practical points for travel. Choosing to be billed in your home currency at a foreign terminal — dynamic currency conversion — almost always costs more than letting your card issuer convert, so decline it. And rates move: for a large transfer, the difference between two days can exceed any fee, which is worth watching if the timing is flexible. For anything material, get the provider's actual quoted rate rather than working from a reference figure.
