A Scalable Vector Graphic (SVG) is a type of graphic file. Instead of storing an image pixel by pixel, they use a special type of data to ensure that resizing an image will not affect its quality—in other words, you can make them as big as you want without any blurriness.
Typically, SVGs are seen as logos, icons, and shapes. All shapes in our shapes panel are SVGs, and we have special tools to edit them. To learn more, see our Support Center Article about Editing an SVG.
