Questions

All questions
Is it really free?

Yes. There is no account, subscription, payment or trial. The tool runs in your browser, so it costs us very little to offer.

Is anything uploaded?

Not unless you choose to. The camera connection, the reading and the result stay in your browser. After a reading you can tap Share result to send the camera’s model, firmware and whether it worked, which helps us grow the camera list. It never includes the count, serial number, photos or anything about you, and you can see exactly what’s sent before you tap. Read the privacy notice.

Which browsers work?

Browsers built on Chromium that support WebUSB, such as Google Chrome and Microsoft Edge on macOS, Windows, Linux and ChromeOS. Firefox and Safari don’t support WebUSB, and nothing on iPhone or iPad can connect to a camera this way. Chrome on Android supports WebUSB with a USB-OTG adapter, but we haven’t tested it.

Which cameras are supported?

We list every camera we have tested, feature by feature, on the supported cameras page. Our first test camera is the Canon EOS 60D. Other cameras that connect over PTP (most Canon EOS bodies, and many others) can be tried; “not yet verified” doesn’t mean it won’t work. Not every camera reports a shutter count over USB, and we never assume support just because a camera is recognised.

Why didn’t the count change after I took photos?

Some cameras only refresh the counter they report over USB when they are switched on. On our EOS 60D, switching off and on, then reconnecting, brings it up to date. Read the full explanation in why a shutter count doesn’t change.
