Currency Converter
Convert 30+ currencies on daily ECB reference rates, with the rate and its date shown. 100% free, no signup. Everything runs in your browser.
Loading the tool…
Enter an amount, pick your two currencies from around 30 majors, and this free converter shows the result using European Central Bank reference rates, with the rate and its date printed right under the answer. A swap button flips the direction in one click, and a small table below shows a few common pairs at a glance, so checking USD to GBP and then EUR to AUD does not mean re-entering everything.
Full transparency, because this tool is the odd one out on my site: it fetches data over the network. Every other tool here runs entirely offline in your browser, but exchange rates change daily, so this one pulls the latest ECB reference rates from the free Frankfurter API. What it fetches is the rates and only the rates; the amounts you type never leave your browser. And to be equally honest about the rates themselves: these are daily reference figures for information, not live market ticks and not what your bank or card will actually charge. For splitting a dinner bill once you are abroad, my tip calculator covers the local side.

Why use our currency converter?
The rates come from a source you can actually audit. The European Central Bank publishes euro reference rates every working day, they are the standard benchmark used in news reports and financial documents across Europe and beyond, and you can inspect them yourself on the ECB's reference rates page. Most converter sites bury where their numbers come from; I would rather show you the source and let you check my working.
Printing the rate and its date under every result is a small feature with outsized honesty value. A number without a date invites you to assume it is live. Seeing "1 USD = 0.79 GBP, ECB reference rate for 8 August" tells you exactly what you are looking at, which matters on weekends, when the most recent rate is Friday's.
The privacy design took actual thought and I am a bit proud of it. The tool requests the day's rate table from the Frankfurter API, an open, keyless service built on ECB data, and then every conversion you perform happens locally against that table. Type a salary, a house price or an invoice total and that figure stays on your machine; the network only ever saw "send me today's rates".
The swap button and pairs table remove the fiddly parts. Anyone comparing prices flips direction constantly, and one click beats re-selecting two dropdowns. The common pairs table answers the second-order questions, like what the pound is doing against the euro, without any extra input.
No signup, no limits, no adverts pretending to be buttons. Convert once or two hundred times; the tool neither knows nor cares.
Who is this tool for?
Travel planning is the big one. Pricing hotels in euros, tours in Canadian dollars or a rail pass in pounds against your home currency tells you what a trip really costs, and daily reference rates are exactly the right precision for budgeting. When I was pricing accommodation for a trip to Portugal, I kept this open in one tab and ran every listing through it; the pairs table meant I always knew roughly where the euro stood without retyping.
Freelancers and small businesses working across borders use it to sanity-check quotes and invoices. If a US client offers 3,000 dollars and you live in the UK, the reference rate tells you what that is worth before fees, a fair baseline for negotiation even though the money that lands will differ slightly. Add local sales tax with my sales tax calculator when quoting gross figures.
Online shoppers hit foreign prices constantly: a US site listing in dollars, an Etsy seller in euros, eBay listings in pounds. A ten-second conversion reveals whether that "bargain" survives the exchange rate, and my discount calculator stacks the sale percentage on top so you see the true final cost.
Anyone following financial news uses it as a quick reference. When a headline says the pound hit a multi-year low against the dollar, converting a few round amounts makes the story concrete, and because these are the same ECB figures journalists cite, your numbers will match theirs.
Frequently asked questions
From the European Central Bank's daily euro reference rates, delivered via the free Frankfurter API. The ECB publishes these every working day around 16:00 central European time, and they are the standard benchmark rates used in financial reporting. The date of the rate you are using is always shown with the result.
No, and any converter that implies otherwise is misleading you. Banks and card networks apply their own rates plus fees and margins, so the money that actually moves will differ, usually by one to three percent. Reference rates are the fair midpoint to compare those offers against, not a promise of what you will pay.
Because ECB reference rates are published once per working day, not streamed live. This tool is built for information, planning and comparison, where daily precision is exactly right. If you are timing an actual currency trade, you need a live market feed, and honestly, you need a broker rather than a browser tool.
No. It fetches the day's rate table over the network, which is the one and only network request, and then all conversions run locally in your browser against that table. The amounts you enter, whether pocket money or a house deposit, never leave your device.
Around 30 majors covered by the ECB reference list, including USD, EUR, GBP, CAD, AUD, NZD, JPY, CHF, SEK, NOK and the other currencies most people in the US, UK, Canada and Australia actually convert. Exotic and pegged currencies outside the ECB list are not included, and I would rather omit them than invent numbers.
The ECB does not publish rates on weekends or on TARGET closing days, so the most recent reference rate stands until the next working day. The tool shows you the date precisely so this is never hidden, rather than letting a Friday number masquerade as a Sunday one.
ECB reference rates are widely accepted for record-keeping and many tax authorities publish guidance on which rate sources they accept, but requirements vary by country and situation, so check your local rules. For generating the invoice itself, my invoice generator handles the layout while you supply the agreed rate. Treat this answer as record-keeping context, not tax advice.
