Rates fetched from a public exchange-rate API (updated daily on weekdays) โ the amount you enter never leaves your browser, only the currency codes are looked up.
Every time you change the amount or either currency, the tool calls a public exchange-rate API for that currency pair and shows the converted amount alongside the per-unit rate and the date the rate was published; picking the same currency on both sides skips the network call entirely and just echoes the amount back.
Free, unlimited, no account. If this saved you a paid tool, a small thanks is appreciated.
