Canva is an online graphic design platform that allows users to create social media graphics, presentations, and other visual content. Users can sign up with an existing account or create a new Canva account with an email address and password. The platform provides templates and designs that users can customize by editing text, images, colors, fonts, and layouts. Users can also upload their own images and add multiple design elements like shapes, icons, and backgrounds. When the design is complete, users can share, download, or publish their creations.
