What is the Difference between a Vector or Raster File ?

Vector image/s OR. Raster image/s

Digital image files, categorized as one of two types: raster or vector. The main difference is how the image is built, that is either from pixels (raster) or a mathematical grid (vector)

Vector File Image

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 color to build an image. Because the mathematical formula recalibrates to any size, a vector image can be scaled up or down without impacting its quality.

Use: Because the resolution of vectors remains the same when resized, this makes them suitable for a wide variety of printed formats.

Some projects combine both raster and vector images. For example, a brochure may use vector graphics for the company logo but raster files for photography.

Raster File Image

Raster file is created by pixels which is/are tiny, individual colored dots that form the details of images or photos. The higher number of pixels an image has, the better the quality of the image. These type of files are well-suited for product photography because of their high quality and workability. They are flexible to edit and manipulate as the pixels themselves can be edited. However, the disadvantage to this file type is that when resizing the resolution can be affected and cause pixilation and blurriness.

Use: Digital uses are usually raster files for example the images you see online are often raster. They are also are commonly used for editing images, photos, and graphics.

Frequently Asked Questions

How do you know if an image is a vector? Enlarge an image to a scale of around 200% using your desktop or phone screen. You’ll know it’s a vector image if the resolution stays intact, with clean edges and solid colors. If the image gets pixelated, it’s most likely a raster file.

Another way of knowing if it is a vector is by the file extension - like if any of those listed above.

Is a PDF a raster or vector? It depends on the program used to create the document because PDFs can also be saved as raster files as well as a vector file. For example, any PDF created using Adobe Photoshop will be saved as a raster file.

Color models

A color model is a system used to describe a color. For example with Red, Green and Blue (RGB) elements or Cyan, Magenta, Yellow and Black (CMYK). It also determines how the colors and hues in an image appear on different screens.

When choosing a color model for your image/logo, you need to know your file type and whether your images will be digital or printed.

CMYK: for printed product images

CMYK (cyan, magenta, yellow, and black) color model is best for when printing. As the printer prints a photograph, the machine combines the colors to create the preferred color.

RGB: for digital product images

RGB (red, green, and blue) color model is ideal for any images/logos digitally on a screen. RGB uses the light source from the screen to manipulate color saturation, vibrancy, and shading

Same image in two color models - you can see the shift in colors from one model to the other. -- Some are more obvious and different than others.
