Canva is an Australian design company founded in Sydney in 2013 by Melanie Perkins, Cliff Obrecht and Cameron Adams, built on the observation that most people who need to make something look good will never learn professional design software. Its browser-based editor combines templates, drag-and-drop editing and a vast stock library so that presentations, social posts, documents and videos can be produced by people with no design training. The platform now serves well over two hundred million monthly users across free, subscription and enterprise tiers, has added the Magic Studio generative AI features and whiteboards, and acquired the professional design suite Affinity in 2024.
