Currency Converter Calculator & Exchange Rates by Currency.Wiki

🌍 Currency.Wiki turns your browser into a complete currency toolkit — live conversion, a built-in calculator, exchange-rate charts, and AI that reads prices directly from any webpage. Convert prices without leaving the page: compare international products, check overseas invoices, plan a travel budget, or monitor exchange rates, all in one place.

Supporting 170+ currencies, 78 languages, and built-in privacy protection, Currency.Wiki helps you understand prices anywhere on the web without constantly opening a new tab.

🧮 NEW: Built-In Currency Calculator

Do the math and the conversion in one place. Tap the calculator icon for a full numpad with addition, subtraction, multiplication, division, percentages, and instant conversion between any two currencies. Type an expression like 19.99 × 3 and watch the converted total update live as you calculate.

The calculator works with your physical keyboard, remembers your last calculation, keeps a history you can copy anytime, and converts every result instantly. Ideal for splitting a restaurant bill abroad, totaling a shopping cart, working out a discount, or checking international pricing.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

💱 Live Currency Converter

Open the popup for instant conversion between 170+ world currencies. Star your favorites, drag to reorder them, set your default base, and copy any conversion with one click. Real-time mid-market exchange rates refresh throughout the day, and you can choose Standard, Compact, or Slim layouts depending on how much you want on screen.

Whether you're shopping, traveling, freelancing, investing, or sending money internationally, the ones you care about are always one click away.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔍 AI-Powered Price Detection (Smart Scan)

Most converters only work inside their own popup. Currency.Wiki reads the actual webpage. Smart Scan detects every price on a page — even a long product listing — and converts them all with a single click. No copying, no pasting, no manual math: just click Smart Scan and every detected price is instantly shown in your own currency.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🏷 On-Page Conversion

Choose how conversions appear as you browse.

Hover Cards — hover over any detected price to instantly see multiple converted currencies, live exchange rates, country flags, and quick copy options.

Inline Mode — show a converted price beside every detected amount automatically, no clicking required.

It even recognizes a store's real currency on Shopify and WooCommerce sites, so a "$" that's actually CAD, AUD, or ILS is converted correctly instead of defaulting to USD.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📊 Interactive Exchange Rate Charts

See how a rate has moved before you make a decision.

Free history: 24 hours, 7 days, 30 days, 90 days, and 1 year.
Pro history: 3 years, 5 years, 10 years, and 15 years.

Longer history helps you spot long-term trends and compare market cycles before you convert or buy.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📋 One-Click Copy — Your Preferred Format

Copy conversions exactly how you need them:

• Code — 369.99 ARS
• Symbol — AR$369.99
• Number — 369.99
• Full conversion — 369.99 USD = 548,339.66 ARS

Copy a single conversion or your whole list — ideal for spreadsheets, invoices, reports, and messages.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

📤 Export Results (PRO)

Export everything Smart Scan finds as CSV, HTML, or TXT — ready for spreadsheets, accounting, price comparisons, or your own records.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☁ Cloud Storage (PRO)

Save exported files straight to Google Drive, Dropbox, or Box. Files stay in your own cloud account, and the extension only ever accesses files it creates — it never browses your personal documents.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

✍ Custom Exchange Rates

Prefer to work with your bank's rate instead of the market rate? Set your own rate for any currency pair — useful for accounting, bookkeeping, fixed contracts, or company reimbursement rates. Custom rates are clearly labeled, and one click restores live market rates.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔒 Built-In Privacy Protection

Currency.Wiki automatically disables itself on more than 1,000 banking, brokerage, tax, and financial websites, so it never runs where your sensitive information is displayed. Need it on for a moment? Enable it for 15, 30, or 60 minutes, and protection turns back on automatically when the timer ends.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🌐 Available in 78 Languages

Every menu, label, setting, and currency name is fully translated into 78 languages, including full right-to-left support.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
