Currency Converter — Real-Time Exchange Rates from Central Bank of Brazil

Convert currencies online with real-time exchange rates from the Central Bank of Brazil (PTAX). Our free currency converter supports 30 currencies including USD, EUR, GBP, JPY, ARS, CLP, COP, MXN and many more — all using official PTAX closing rates published daily by the Banco Central do Brasil.

The PTAX rate is the reference exchange rate in Brazil, used by banks, companies and individuals for currency conversion. It is calculated as the weighted average of interbank foreign exchange transactions and is published by the Central Bank through the Olinda open data portal. Our tool queries this official API and displays both the buy rate (cotação de compra) and sell rate (cotação de venda).

Exchange rates are cached for 1 hour to ensure fast responses. The tool automatically fetches the most recent available quotation (within the last 7 days) to handle weekends and holidays when markets are closed. All conversions involving two foreign currencies (e.g., USD to EUR) are calculated through BRL as a bridge currency using official PTAX rates.

This converter is ideal for travelers planning a trip abroad, importers and exporters checking current exchange rates, developers integrating currency data, or anyone who needs to know how much their money is worth in another currency.

Frequently Asked Questions

What is the PTAX rate?
PTAX is the official reference exchange rate published by the Central Bank of Brazil (Banco Central). It represents the weighted average of interbank foreign exchange transactions and is used as a benchmark by banks, companies, and government institutions for currency conversions.
How often are the exchange rates updated?
The PTAX rates are published by the Central Bank on business days. Our tool caches rates for 1 hour and automatically fetches the most recent available quotation. On weekends and holidays, the last available business day rate is used.
Can I convert between two foreign currencies (e.g., USD to EUR)?
Yes. When converting between two foreign currencies, the tool uses BRL as a bridge currency. It converts the source amount to BRL first using the sell rate, then converts BRL to the target currency using the buy rate — both using official PTAX quotations.
