How it works
Pick a currency to convert from and one to convert to, enter an amount, and the result updates instantly using the latest fetched rates — no extra request per keystroke. Use the swap button to flip the two currencies without retyping. Rates are sourced from the European Central Bank via the free Frankfurter API and are typically refreshed once per business day; use the "Refresh rates" button to pull the newest values at any time.
Frequently asked questions
Is this free to use?
Yes. There's no sign-up and no limit on how many conversions you run.
Where do the exchange rates come from?
Rates are sourced from the European Central Bank via the free Frankfurter API, and are typically updated once per business day (rates aren't published on weekends or ECB holidays).
Do you store what I type?
No. Amounts and currency choices stay in your browser. The only network request this page makes is a call to the Frankfurter rates API to fetch current exchange rates — no personal data is sent. See the privacy policy for details.
What happens if I'm offline or the rate feed is down?
RateSwap keeps the last successfully loaded rates cached in your browser and keeps working from them, with a note showing their date, until a fresh fetch succeeds.
