Google Photos allows you to effortlessly transform your favorite photos into stunning collages by selecting up to 6 photos on mobile or up to 9 photos on desktop. The app automatically creates a collage using pre-designed layouts, but you can also choose from other options. Additionally, you have the ability to edit each photo individually by adjusting brightness, contrast, rotating, and cropping. Once you’re satisfied with your collage, simply save it to enjoy and share with others.
