Exchange-rate data powered by Frankfurter.dev.
Disclaimer: Rates are intended for informational and developer utility purposes. Your browser loads only static JSON files from this server — no third-party requests. For financial transactions, consult your bank.

How It Works

Konvi periodically fetches exchange-rate data from Frankfurter.dev server-side and serves it as static JSON. Your browser only loads local files from konvi.ch — it never contacts any third-party service.

Privacy First: Your browser makes zero requests to external services. All rate data is pre-fetched server-side and served as static files.

200+ Currencies: Frankfurter aggregates data from 84 central banks covering 201 currencies, including legacy currencies for historical conversions.

Historical Rates: Select any historical date going back to 1948 using the date picker. The tool loads the exact rate for that date, or the nearest previous publication date if none exists.

Rate Charts: Visualize rate trends from 3 days to the full available history. Chart data is precomputed server-side for instant loading.
