Web graphics are generally not suitable for professional printing. Until high-speed internet became so widely used it was critical to keep file sizes low to keep load times down online. To recap, logo files should always be vector-based and SVG files can be used to display vector graphics online. Vector graphics have a few downfalls: First and foremost the binary code data used to save them for on-screen use is larger than for a raster image that looks the same, so the file size is larger. 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) In summary, raster images are best for photographs and images with complex color blends, while vector images are best for graphics, logos, and illustrations that require precise lines and shapes.Graphics Interchange Format (.gif, GIF). Soft gradients and bold, complex color patterns are easy to pull off when working on a pixel-by-pixel (or bit-by-bit. Raster images are capable of more subtle blending and shading and use shadows and depth like a vector can’t. Joint Photographic Experts Group (.jpg, JPEG) What’s more, raster images are especially useful when it comes to editing as each individual pixel can be altered.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. Unlike raster graphics, vector images are resolution independent, meaning you and I dont have to worry about quality, pixels, resolution, or re-sampling. 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? Raster and Vector Images Have Their Respective Strong Suits. Whereas a raster graphic has to store colour information for every single one of the millions of dots that make the image, a vector graphic only has to store.
