What is Canva?Canva is a free graphic design web application that allows you to create invitations, business cards, flyers, lesson plans, banners, and more using professionally designed templates. You can upload your own photos from your computer or from Google Drive, and add them to Canva's templates using a simple drag-and-drop interface. It's like having a basic version of Photoshop that doesn't require Graphic designing knowledge to use. It’s best for nongraphic designers.
