Removing the background in an image typically involves knowing how to use photo-editing software or enlisting the help of someone else who does. Now there’s another solution: using AI.
Remove.bg is a website whose sole purpose is to remove the background from images. To use it, you just upload an image with people in it and the site will automatically figure out where the people are in the picture and then remove the background, leaving you with a downloadable PNG of your subject with a transparent background.
As you might image, your mileage may vary. The Verge, which initially spotted the tool, notes that it has trouble with images that have fuzzy backgrounds.
That said, if you have an image with a clear foreground then it can make editing a photo a ton easier.
