Helpful tips to make your Canva graphics work well with Canvas and other applications you use often:

Graphics and images are measured in pixels (abbreviated px). The larger the pixels, the better the quality of the image, and the larger it will be on the page.
When downloading a still image, choose PNG. The image will be better quality.
When downloading an image with movement, choose GIF.
