RATE — Przelicznik Walut i Kursy Walut

Zaznacz dowolną cenę na dowolnej stronie i przelicz ją od razu — 160+ walut, BTC i ETH, kursy średnie.

Highlight any price on any web page and see what it actually costs you. No tab-switching, no copy-pasting, no calculator. Select a price and a small tooltip shows it in your own currency at the mid-market rate — then adds your bank's markup, so the number you see is the number you'd really pay. That last part is what most converters leave out. Banks and cards add 1–3% on top of the mid-market rate, and a conversion that ignores it is quietly wrong. Enter your provider's percentage once and every figure accounts for it. Key features • Highlight to convert — select any amount on any page for an instant conversion. • Your bank's real cost — enter your card or bank markup once and see what you'd actually be charged. • 160+ currencies — including the Russian ruble, UAE dirham, Vietnamese dong and other currencies most converters skip, plus the USDT, USDC and DAI stablecoins. • Private by design — no accounts, no analytics, no advertising, no third-party scripts. The extension downloads published rate tables and does the maths on your machine, so the amounts and currencies you look at never leave your browser. • Works offline — rates are cached locally, so conversions keep working without a connection. • Stays out of the way — nothing happens until you highlight something. No auto-hover, no page rewriting, no layout changes. Where the rates come from Mid-market reference rates published by the European Central Bank, extended with a second published source for the currencies the ECB does not cover, and CoinGecko for stablecoins. Rates are published daily — the extension does not claim real-time pricing, because the underlying data is not real-time. Perfect for online shopping, booking travel, buying software priced in another currency, or importing goods.
