How do you increase the size of a vector image? This is why a lot of designers prefer to convert their images to vector before printing them out. Vector graphics are used by artists who are creating illustrations, logos, and other designs that are going to be printed on big surfaces. And because of this, if you zoom in or out, the lines, curves, or points always remain smooth. They form shapes based on mathematical equations. Upscale your images for free with AI What is a vector image?Ī vector image or graphic is a type of image defined on a plane, connected by lines and curves. Although with AI tools, it is possible to increase your artwork resolution. While it's easy to make an image smaller, increasing the size usually means decreasing the resolution. Let's pretend you have a raster image that is 300 x 300. How do you increase the size of a raster image? They are viewable using a bitmapped display or another medium. A raster, also called a bitmap image, represents a rectangular grid of pixels. 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.Why is this difference important and what does it actually mean? What is a raster image?Ī raster image is a term in computer graphics and digital photography. 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).
