About this extension
Ratevert converts selected currency and crypto prices on any webpage. Highlight an amount such as $21.99, EUR 12.50, or 0.000018 BTC to open a compact conversion card with live exchange rates, automatic source detection, themes, and optional fee or tax calculations.
Ratevert TV Mode turns a browser, monitor, or storefront TV into a customer-facing currency exchange board. Exchange offices and physical currency counters can set buy and sell rates, choose a local currency, switch between dark and light displays, and open a clear fullscreen board. Auto Rates can apply a custom spread around Ratevert currency data, while saved boards and public links help keep shop screens synchronized.
