Everything you need to know about the TwentyOneTools Currency Converter. Search below or browse the common questions.
Your typed amounts stay in your browser. The converter does not ask for bank details, card details, or personal finance data.
No. The calculation runs in the page after rates are loaded. The only network request the tool tries to make is to fetch exchange-rate data.
The homepage attempts to load current rates from a public exchange-rate API. If that request is unavailable, built-in demo rates keep the converter usable for layout testing and rough estimates.
Choose the currency you have, choose the currency you want, enter an amount, then press Convert currency. The result and the rate used appear underneath.
Yes. Use the swap button between the two selectors to flip the from and to currencies instantly.
The generated homepage uses a 25-per-day free counter, matching the original layout pattern while making sense for currency checks.
The converter includes major global currencies such as USD, EUR, GBP, JPY, AUD, CAD, CHF, CNY, INR, SGD, NZD, MXN and more. See the currencies page for the supported list and rate notes.
Banks, card providers, and payment apps often apply spreads, fees, or their own refresh schedule. Treat this tool as a quick estimate, not a guaranteed settlement rate.
This generated version is focused on fiat currencies. Crypto pairs could be added later with a crypto-rate API and matching picker entries.
Refresh the page and check your internet connection. If the public API is unavailable, fallback demo rates will still let the interface work.
