How it works

Complete the job in three clear steps

  1. Enter or choose an amount, currency pair, and optional historical date.
  2. Use the available controls to create a locally calculated reference conversion.
  3. Review, copy, or download the result before relying on it.

Important

Check the result before relying on it

Scan-test generated codes before printing or distribution. A generated barcode does not register identifier ownership, and decoded external links should be checked before opening.

Questions

About this tool

Is this the rate my bank will use?

No. Frankfurter provides reference rates. Banks, cards, brokers, and payment services may use different timestamps, spreads, fees, rounding, or buy/sell rates.

What data leaves my browser?

Only the selected base code, quote code, and optional rate date are requested. The amount is multiplied locally and is not placed in the API URL or body.
