Multi-Currency Converter

Enter an amount, choose a base currency, and select several target currencies to get an individual conversion for each one: amount × exchange rate. Exchange rates are fetched from Frankfurter (api.frankfurter.dev, no key, no cost), a public provider that blends several sources; a fixed rate is never hardcoded in the code. Each result shows the currency code, the converted value, the exact rate used, and the observation date for THAT specific pair — different pairs can show different dates, and that's normal, not an error. The amount you enter is never sent to the provider: only the base currency and the target currency codes are requested; the multiplication happens in your browser. If the provider doesn't return a rate for a currency, that currency is marked as unavailable instead of a number being invented. These are rough reference rates, not a real-time trading quote or the exact rate your bank, card, or exchange house will apply, which may add a margin or fee.

The amount is never sent to the exchange-rate provider; only the base and target currencies are requested. The conversion happens in your browser.

Requires an internet connection to fetch updated rates. These are reference rates (the latest available from the provider), not a real-time quote or the exact rate your bank, card, or exchange house will apply, which may add a margin or fee. Each result shows the observation date received for that pair — different pairs can show different dates.

The amount you enter is never sent to any server. Only the base and target currency codes are requested from an external exchange-rate provider (Frankfurter) to get the rate — the conversion itself is calculated on your device.

Frequently asked questions

Where do the exchange rates come from?
From Frankfurter (api.frankfurter.dev), a public, key-free provider that blends several sources. The tool never stores or hardcodes a fixed rate in the code.
Is this the exact rate my bank or card will give me?
No. It's a rough reference rate, not a real-time trading quote; your bank, card, or exchange house may apply a different margin or fee.
Is my amount sent to any server?
No. Only the base currency and the target currency codes are requested from the provider to get the rate; the multiplication by your amount always happens in your browser.
Why can two target currencies show different dates?
Because each base→target pair has its own most recent observation date at the provider; no single global date is forced, and showing different dates is the correct behavior, not a bug.
