![]() ![]() Raster files display a wider array of colours, permit greater colour editing, and show finer light and shading than vectors - but they lose image quality when resized. An easy way to tell if an image is raster or vector is to increase its size. If the image becomes blurred or pixelated, it’s most likely a raster file. The resolution of a raster file is referred to in DPI (dots per inch) or PPI (pixels per inch). If you zoom in or expand the size of a raster image, you start to see the individual pixels. One of the main differences between raster and vector files is their resolution. They represent images in very different ways, so there’s a lot to consider when deciding which one to use. Some of the main differences between raster and vector include: Raster and vector files are the two most popular formats used for visual content. What is the difference between raster and vector files? Vector files use mathematical equations, lines and curves with fixed points on a grid to produce an image. There are no pixels in a vector file. A vector file’s mathematical formulas capture shape, border, and fill colour to build an image. Because the mathematical formula recalibrates to any size, you can scale a vector image up or down without affecting its quality. Raster files are images built from pixels - tiny colour squares that, in great quantity, can form highly detailed images such as photographs. The more pixels an image has, the higher quality it will be, and vice versa. The number of pixels in an image depends on the file type (for example, JPEG, GIF, or PNG). Raster vs. vector files: frequently asked questions.What is the difference between raster and vector files?.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. Raster images are best for digital photos and print materials. Their native files are needed for coin designs, laser engraving, t-shirts, patches, etc. They're also used in lower thirds for videos, web-based objects and rendering 2D or 3D computer animation. Raster-based software (e.g., Adobe Photoshop)Ī vector graphic's small file size and scalability make it uniquely suitable for use in digital printing from business cards to billboards.Vector-based software (e.g., Adobe Illustrator). ![]() Digital printing (e.g., business cards, billboards).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. Resolution limits the size the image can be scaled up without being able to see pixels. The lower the number of pixels, the lower the 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. Each image can only contain a fixed number of pixels the amount of pixels determines the quality of the image. These images are created by digital cameras, by scanning images into a computer or with raster-based software. Pixels appear like little squares on graph paper when the image is zoomed in or enlarged. Raster images are made of pixels or tiny dots that use color and tone to produce the image. Because they consist of lines and anchor points, the size of the file is relatively small. These graphics are also device-independent, which means their quality doesn't depend on the number of dots available on a printer or the number of pixels on a screen. Their lines are sharp, without any loss in quality or detail, no matter what their size. Because these graphics are not based on pixels, they are known as resolution independent, which makes them infinitely scalable. These graphics consist of anchored dots and are connected by lines and curves, similar to the connect-the-dot activities you may have done as a kid. Vector graphics are also known as scalable vector graphics (SVG). ![]()
