The short video below shows you exactly how I do it on an iPad. Any phone or tablet should make this easy and then you can use another device to edit the slides (and possibly add the comic elements.) Here are the steps:
- Go to remove.bg.
- Tap the Select a Photo button and choose the option to take a photo.
- The site will automatically remove the background. I've had great results so far! Copy the image that has no background.
- Paste it into a slide using the Google Slides app.
Ideally you'll have some other background you're pasting into. Those slides can all be set up ahead of time as needed either on the same device or a computer.
