How It Works & Educational Guide
How Nexifr's Currency Converter works and when to use it — practical guidance for getting accurate, reliable results every time.
01What problem does Currency Converter solve?
When you need to convert between 80+ currencies with live exchange rates — updated every 30 minutes, the challenge is finding a clear, no-account workflow with useful output. Nexifr's Currency Converter is designed to make that workflow quick and understandable. The browser fetches current exchange rates from open.er-api.com's public API. No personal data is transmitted. Rates are cached in sessionStorage for 30 minutes.
02How it works & data handling
• Data handling: Live exchange rates are fetched directly from open.er-api.com — no personal data is sent, and rates are cached in your browser for 30 minutes. • Clear output: Results are formatted for immediate use — download a file or copy the result where available. • No account required: You can use the tool without creating a Nexifr account.
03Common questions
• Are exchange rates live? Yes — rates are fetched from open.er-api.com's public API and cached in your browser for 30 minutes. A static fallback is used if the API is unavailable. • Which currencies are supported? Over 80 currencies including USD, EUR, GBP, INR, AED, JPY, CNY, CAD, AUD, CHF, SGD, and many more. • Why do exchange rates differ slightly from my bank? These are mid-market rates — the midpoint between buy and sell rates. Banks add a margin (typically 1–5%) on top. Use these rates as a reference, not for financial transactions.
