Frequently Asked Questions
Does this work offline?
Yes. The conversion math runs entirely in your browser using the rate shown, so once the page has loaded you can convert with no internet connection. The rate field starts with a built-in approximate value you can edit to the exact rate.
Where does the live rate come from?
Only if you tap "Fetch live rate." It then requests once from frankfurter.dev (European Central Bank reference rates) with open.er-api.com as a fallback. Nothing leaves your browser until you click that button.
Why is the starting rate slightly off?
The built-in rates are approximate defaults so the tool is useful the instant it loads. Enter the exact rate from your bank, or tap fetch for today's reference rate.
What about exchange spreads?
Banks and fintech apps add 1-3% on top of the reference rate. Divide the rate by about 1.02 for a more realistic consumer quote.
