Currency Converter

Convert between world currencies with live exchange rates.

Currency Converter is a math & finance utility that does its own work in your browser but needs to pull live reference data from a public API — think exchange rates, geolocation, time zones, or similar information that only makes sense when it is fresh. Everything you type stays in your tab; the network call is a reference lookup, not a file upload.

That lookup means the tool is not a true offline utility: an internet connection is required, and the API provider sees that a request came in (though not what you typed). We log nothing on our side — no account, no email form, no ads, no watermark, and no "freemium" tier. If you need to work without any outbound network traffic, this tool is not the right pick; most of the catalog is on-device, but a handful (this one included) are explicit about depending on live data.
