This is because your raster image has a set number of pixels (resolution), and upscaling the image requires the image to “create” more pixels to meet the input size. While it’s safe to downscale a raster image without sacrificing quality, upscaling a raster image heavily pixelates the image. In a nutshell, raster images are best for detailed graphics, photographs, and scanned artwork. They offer in-depth detail and color that vector graphics aren’t able to provide. Raster images are comprised of a varying range of color, blending seamlessly into each other. Zooming in on a raster image, the pixels (the square blocks in the image above) become clear and the details in the image become blurry. When these pixels are combined, they form the images you see on every digital screen (monitors, TVs, cameras, etc).Īdditionally, digital cameras create raster images and every photo you see online is raster. When the different colors of light are combined, you get a huge range of color. Each pixel has a different value for red, green, and blue light. When you’re watching TV or looking at something online, you’re looking at thousands of little pixels with different values to convey color. Raster images are comprised of tiny units called pixels. Unlike vector graphics, raster images are photo-realistic. If this doesn’t work for you, graphic designers would be happy to help. You would have to do this by using a vector-based editor such as Adobe Illustrator or CorelDRAW. Or you can later convert it by re-creating it as a vector graphic. Your artwork would have to either be made from the start in vector format. While you can turn any vector file into a raster image by overriding the file type, this unfortunately doesn’t work the other way around. This allows you to easily scale up and down your logo without compromising the quality.ĭesigners and printers will often ask for your logo in vector format to ensure your logo displays perfectly with whatever they’re designing/printing.Ī common pain point that people run into is thinking they can override a raster image and convert it to vector by changing the file format. Having your logo in vector file format is an absolute must. Some common situations where you’ll need vector files: custom branded apparel, customized promotional products, laser engraving, large-scale designs like banners/signs, and vehicle wraps. Again, this is because the line-art is formed of mathematical formulas rather than pixels. No matter what size you scale them to, the quality remains the same and consistent. You can blow them up to be 10′ x 18′ or 3″ x 4″. The best thing about vector graphics is their ability to endlessly scale in size to suit your needs.
