Currency Converter
Queries a public record from our server — not your files.
Convert an amount between thirty currencies at the European Central Bank's daily reference rate — a published, citable number rather than an anonymous one that flickers. The rate table is fetched from our server once when the page loads, so typing a different amount converts instantly without anything leaving the page; only switching the "from" currency asks for a new table. No amount you type is ever sent anywhere, and the request that is made contains nothing but a currency code.
This tool is an exception on this site. Everything else here runs entirely in your browser, but a web page cannot query DNS, read a certificate or see another site’s response headers — so the name or URL you enter is sent to our server, which looks up the public record and sends the answer back. The answer is cached for up to a minute. No file of yours is read, uploaded or stored, and there is no account.

Frequently asked questions
Does this send my data anywhere?+
The amount is never sent. Our server is asked for one thing — the rate table for the currency you are converting from — and every calculation happens in the page afterwards. That request contains a three-letter currency code and nothing else.
Why does my bank give me less than this?+
Because this is a reference rate: the mid-point of the market, which is not a price anybody can transact at. Banks and card networks add a margin, typically 1% to 3%, and a bureau de change at an airport rather more. The gap is the fee, whether or not it is described as one.
How often does the rate update?+
Once per working day. The European Central Bank publishes its reference rates in the early afternoon, Central European Time, and they do not move again until the next working day — so the figure is identical all weekend. Anything advertising a rate that changes by the second is quoting a trading feed, which is a different thing.
Why is my currency not listed?+
The list is exactly what the ECB publishes: thirty of the most traded currencies. Currencies that are pegged, thinly traded, or subject to capital controls are not in it, and no reference rate for them would be meaningful anyway.
Can I use this for accounting or tax?+
Check what rate your tax authority requires first — many specify their own published rate for a given day, or a monthly average, and will not accept another source. Where the ECB rate is acceptable, the report names the source and the publication date, which is the part an auditor asks for.
