Good news for those who don’t want to mess around with cables or think about photo transfer or even worse backups at all.
You can now upload photos from your Canon camera to Google Photos by using the image.canon app for Android and iOS. From Google:
If you own a DSLR or point-and-shoot camera, you know that getting your photos backed up can be a process. You often need cables or adapters to take them off of your camera or SD card and save them, and it might take a number of steps to get it all done. We’ve worked with Canon so you can easily upload the moments captured on your Canon devices directly to Google Photos over Wi-Fi—no plugging in your camera or taking out your SD card.
Compatible Canon cameras are listed here.
However, there are some caveats. First, you need a subscription to Google One to use the service. Next, we do not recommend it because of privacy concerns (what can Google do with your images?). Your mileage might vary.
