A comparison of a vector image versus a raster image. Notice how the vector image on the left is made up of points and lines and appears smooth. Vector graphics are digital art that is rendered by a computer using a mathematical formula. Raster images are made up of tiny pixels, making them resolution dependent and best used for creating photos. This means that if you scale a vector image, it will maintain a smooth, un-pixelated appearance, whereas a raster image will become pixelated.Alt Text: Image of side by side comparison of vector and raster image of the United Coast Guard seal with zoom in on each seal for comparison.

Raster images are made of pixels or tiny dots that use color and tone to produce the image. Pixels appear like little squares on graph paper when the image is zoomed in or enlarged. These images are created by digital cameras, by scanning images into a computer or with raster-based software. Each image can only contain a fixed number of pixels; the amount of pixels determines the quality of the image. This is known as resolution. More pixels result in better quality at the same or larger sizes as the original, but this also increases the size of the file and the amount of space it takes to store the file. The lower the number of pixels, the lower the resolution. Resolution limits the size the image can be scaled up without being able to see pixels. However, a high resolution image printed at a small size will cause the pixels to "cram" together and will make the image look as unprofessional as not having enough pixels in a large image.

A vector graphic's small file size and scalability make it uniquely suitable for use in digital printing from business cards to billboards. They're also used in lower thirds for videos, web-based objects and rendering 2D or 3D computer animation. Their native files are needed for coin designs, laser engraving, t-shirts, patches, etc. Raster images are best for digital photos and print materials. If your project requires scalable shapes and solid colors, vector is the best choice, but if your project requires complex color blends, raster is the preferred format.
It also automates the tweening process and offers support for raster graphics, audio, and video embedding, rich text, and more. It is available on Android, iOS, Windows Desktop, and macOS.
