![]() png file is very small (16kb) and makes for a quick loading page. png file, while the design itself was originally created using a vector editing software. For example, Google’s standard logo on is actually a. It's also common for vector images to be converted to raster images to make them more accessible on the web. As long as the resolution is at least 300 pixels per inch, your image will be able to be printed just fine. In this case, you might want to keep your image a raster file. Converting a photograph to a vector image is possible, but will usually result in a drop in detail. For example, photographs are always raster images. However, there are times when using raster images might be your best option. This difference usually makes vector images a superior option, especially when it comes to print. You could literally increase the size to 3 million x 3 million and all the details would still look sharp (assuming your computer could handle a file that big). Now let’s pretend you have a vector image that is 300 x 300.īecause a vector image is made up of mathematical paths, you can increase the size of the image as much as you want and it would never decrease in quality. 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. Web graphics are generally not suitable for professional printing.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. To recap, logo files should always be vector-based and SVG files can be used to display vector graphics online. Make sure the designer provides vector logo files when updating your logo, and ask your printer to double-check the resolution of images when professionally printed material. With this in mind, consult a graphic designer when in doubt. Raster-based images can be embedded into Adobe Illustrator, and vectors can be placed and even created in Photoshop. Any of the above file types can be exported to a pdf format, so these files can be either vector, raster, or a combination of the two.ĭisclaimer: Graphics software has come a long way, resulting in much line-blurring between programs. The small exception to these rules is the Portable Document Format (.pdf, PDF). Encapsulated PostScript File (.eps, EPS).Graphics Interchange Format (.gif, GIF).Joint Photographic Experts Group (.jpg, JPEG).The purpose of this post is to further explain the difference between these file types and to help determine which type is required for various purposes. Raster graphics, such as digital photographs, are created using a grid of tiny pixels. Vector graphics, such as logo files, use intricate paths of points and lines to create an image. When zoomed in closely, the individual pixels can be observed.ĭigital graphic files will generally fall into two categories-vector or raster. Raster images are made up of tiny squares called pixels and are often referred to as 'bitmap' images. This makes vector files the best format for graphic assets such as illustrations, icons and company logos, as the same file can be used for designs ranging from a mobile app to a large billboard without sacrificing quality or increasing file size. Vector files, made up of points and lines to create paths, can be scaled up and down without losing quality. What is the difference between vector and raster files for graphics?
