Are the rates real-time?

No. Rates are approximate reference values baked into the tool. They are suitable for estimates and quick comparisons but not for financial transactions. For actual transfers, always use your bank or a payment processor with live rates.

How many currencies are supported?

31 currencies covering most of the world's major economies: USD, EUR, GBP, JPY, CAD, AUD, CHF, CNY, INR, MXN, BRL, KRW, SGD, HKD, NOK, SEK, DKK, PLN, CZK, HUF, RON, BGN, TRY, RUB, UAH, ZAR, NZD, THB, PHP, MYR, IDR.

Can I convert between two non-USD currencies?

Yes. The tool converts both currencies to USD internally, then derives the cross rate. For example, EUR→JPY = (1/EUR_rate) × JPY_rate.

How to Convert Currency Online Free — 31 Currencies (2026)

By Rui Barreira · Last updated: 18 June 2026

Converting currencies online is one of the most common quick-math tasks on the internet. Whether you are travelling, shopping internationally, or tracking an invoice in a foreign currency, a simple browser-side converter gives you an instant reference without logging in, uploading anything, or waiting for a server round-trip.

How to Use

Enter the amount you want to convert.
Select the source currency from the “From” dropdown.
Select the target currency from the “To” dropdown.
Click Convert and read the converted amount with the exchange rate used.

How It Works

The converter holds approximate reference rates for 30+ major currencies expressed relative to USD. The conversion formula is: result = (amount / fromRate) × toRate. All arithmetic happens locally in your browser — no data is sent to any server. Because rates are hardcoded rather than live-fetched, the tool works offline and loads instantly.

When to Use a Reference Rate vs. a Live Rate

Hardcoded reference rates are accurate enough for quick mental math, budget estimates, and sanity-checking figures. For actual financial transactions — wire transfers, invoicing, currency trading — always use a source with live rates such as your bank, a payment processor, or a financial data provider. Rates fluctuate throughout the day; a reference rate from a static tool can be off by a fraction of a percent or more during volatile periods.
