About
A no-frills currency converter: enter an amount, pick two currencies, swap them with a tap. Rates are the daily reference rates published by the European Central Bank.
How it works
It calls the keyless Frankfurter API (ECB rates) straight from your browser — no API key and nothing routed through a server of ours. Requests are debounced as you type.
