How to use the currency converter
Quick, honest currency conversion
This converter uses the European Central Bank reference rates, one of the most widely used neutral sources for daily exchange rates. It is built for quick estimates: pricing an invoice, checking a shop abroad or planning a trip.
How to use it
- Type the amount.
- Choose the currency you have in From and the one you want in To. The swap button reverses them.
- Read the converted amount, the rate in both directions and the date of the rates.
- Tap any currency in the list on the right to switch your target currency, or copy the result.
How the rates are kept fresh
Our server downloads the latest rate table from the Frankfurter service, which republishes ECB data, and keeps it for 12 hours. Every visitor is served that shared copy, so no visit triggers an extra call to the provider. If the provider is briefly down, the last copy continues to be served and the tool tells you the rates are older.
Offline and privacy
After a successful load, the rates are stored in your browser. Without a connection, the tool keeps converting with the saved table and shows how old it is. The amounts you type never leave your device.
Things to know
- Reference rates are mid-market. Banks, card networks and money-transfer apps add a margin, so your real rate will be a little worse.
- Rates change daily, and the ECB does not publish at weekends, so Monday morning may show Friday's figures.
- About thirty currencies are supported. Some, such as the UAE dirham, are not in the ECB feed.
- For large transfers, compare providers on the day and confirm the final quote.
Results are estimates and not financial advice.
Frequently asked questions
Where do the exchange rates come from?
From the European Central Bank reference rates, published by the free Frankfurter service. Our server fetches them at most twice a day and shares them with every visitor, so your visit does not call the provider.
How often are rates updated?
The ECB publishes new rates once per working day, around 16:00 Central European Time, with no update at weekends and holidays. The page always shows the date of the rates in use.
Why does my bank give a different rate?
Banks, card networks and transfer services add a margin and use their own timing. Reference rates are the mid-market figure, useful for estimates and price checks, not for what you will be charged.
Does it work offline?
Yes. After one successful load the latest rates are saved in your browser. If the service cannot be reached the tool keeps converting with those saved rates and tells you their date.
Why is my currency missing?
The ECB publishes about thirty major currencies. Currencies such as the UAE dirham, Saudi riyal or Nigerian naira are not included in that feed.
