Some projects combine both raster and vector images. Vector files work better for digital illustrations, complex graphics, and logos. That’s because the resolution of vectors remains the same when resized, making them suitable for a wide variety of printed formats. Many digital cameras automatically shoot and save photos as raster files - and the images you see online are often rasters, too. Raster files are also commonly used for editing images, photos, and graphics. With vector image files, resolution is not an issue. You can resize, rescale, and reshape vectors infinitely without losing any image quality. Vector files are popular for images that need to appear in a wide variety of sizes, like a logo that needs to fit on both a business card and a billboard.ĭigital photographs are usually raster files. 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?.For this reason, vector images are a more common choice when creating T-shirt logos and prints. The square pixels that make up raster images don’t always transfer well to fabrics and clothing. While this creates a highly detailed image, it can also increase the file size and loading speed. Their colors and details can distort when enlarged, reducing the number of ways you can use these images.Ī raster file may include millions of pixels. Unlike vector images, raster files don’t maintain their resolution when resized. The disadvantages of raster files include: Raster files can open in a wide range of programs and web browsers, making it easy to view, edit, and share your images. This lets you enhance and tailor the image to your own needs. You have the power to individually alter each pixel when editing a raster graphic or photograph. The more pixels a file contains, the stronger the image quality. When displayed in the right dimensions, raster files can show off all the intricate details and colors found in high-resolution photos. If you’re thinking about using a raster file in your next project, make you sure you know the upsides and downsides before you start: Advantages of raster files.
