Crypto, built in

Bitcoin, Ethereum and friends sit right next to fiat. Check the BTC price or convert ETH to USD without leaving your browser.

Multi-currency view

Enter one amount, see it in every currency you care about at once. Drag to reorder, drag to swap — your list is remembered.

Smart search

Type "Turkey" for TRY, "Japan" for JPY, or a region like "South America". No need to remember currency codes.

Dark mode & 13 languages

A clean, modern interface that follows your browser language and your theme — light or dark, your choice.

Private & lightweight

No account, no personal data. Your amounts stay on your device; only anonymous, aggregate stats help us improve. A few megabytes of WebAssembly, never in your way.
