Note: Exchange rates are sourced from the European Central Bank (ECB). Rates are updated server-side every 10 minutes (ECB publishes new data ~16:00 CET on business days). Your browser loads only a static JSON file from this server — no third-party requests. For financial transactions, consult your bank.

How It Works

The Currency Converter uses exchange rates from the European Central Bank (ECB), fetched server-side every 10 minutes by an automated script. Your browser only reads a static JSON file from konvi.ch — it never contacts any third-party API.

Privacy First: Unlike most currency converters, your browser makes zero requests to external services. All rate data is pre-fetched server-side and served as a static file.

ECB Rates: The ECB publishes daily reference rates around 16:00 CET on business days. Our server script picks up new rates within 10 minutes of publication.

Historical Rates: The server maintains a rolling 10-day history of daily rate snapshots. The chart and table show how rates have changed over recent days.

Fallback Rates: If the data file is temporarily unavailable, the tool falls back to bundled approximate rates so conversions still work.
