Scratch allows you to make 2D games. The two types of 2D graphics you can create are bitmap and vector images. Bitmap: Bitmap images are made up of pixels. Bitmap graphics are not used that often. The downside is they tend to have a fixed size.

Enlarging raster images can make them look pixelated or fuzzy. Though you may prefer a more robust image editor such as Photoshop or GIMP , which is a free alternative to Photoshop.

Vector: Unlike raster images, vector graphics are not made of pixels. They are made up of data points called vectors that are connected to create lines and shapes. They are the most widely used graphics on Scratch. Scratch supports scalable vector graphic. You can create vector graphics using Adobe Illustrator , or Inkscape which is a free alternative to Illustrator. Start a new graphic in Scratch.
