iOS 11 added the option to scan a QR code with the built-in camera app on an iPhone. However, I couldn’t find an option to scan a QR code from an image saved to my camera roll or otherwise already saved to Files and not something printed or physical external to the phone.

How can I scan a QR code from an image already saved on an iPhone?

The app QR Reader for iPhone on the App Store is quite a powerful QR code app. Check it out.

I use it infrequently, but I'm glad I have it in my toolbox.

Another reader that isn't scammy or tries to advertise / monetize your use is QRafter Pro and it's very solid over years of use.

  • Thanks, @bmike. How is it scummy and monetizes my use? I'm intrigued.

    Both of these readers are awesome. Feel free to roll back or edit my edit if I’m somehow putting your suggestion in anything but top billing. Just wanted a second candidate app to try.

  • I see no problem with your edit or comment @bmike. I just tried QRafter on my iPhone and it is indeed awesome. We make QRafter available on our managed fleet of iPads at work, but I'd never used it myself.

    I don’t see anything in either App Store listing that says it can read an internal image.

    @WGroleau I’ve just tried QR Reader (the first app linked here) and it has a flower icon to import a QR code from a photo already in the photo library. Paired with the screenshot tool, this is a way to read a QR code from any app or website viewed on the same device.
