Raster images are made up of a bunch of tiny pixels, while vector images are made from mathematical paths.
Why is this difference important and what does it actually mean?
Let's pretend you have a raster image that is 300 x 300.
While you could easily make the image smaller, there is no way to increase the size of the image without decreasing the resolution or recreating it entirely.
Now let’s pretend you have a vector image that is 300 x 300.
Because 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. 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).
This difference usually makes vector images a superior option, especially when it comes to print. However, there are times when using raster images might be your best option. For example, photographs are always raster images. Converting a photograph to a vector image is possible, but will usually result in a drop in detail.
In this case, you might want to keep your image a raster file. As long as the resolution is at least 300 pixels per inch, your image will be able to be printed just fine.
It's also common for vector images to be converted to raster images to make them more accessible on the web. For example, Google’s standard logo on Google.com is actually a .png file, while the design itself was originally created using a vector editing software. The .png file is very small (16kb) and makes for a quick loading page. But when it comes to printing, Google would want to use a vector version of their logo.
If you plan on using a logo, text, or illustration for print, we recommend tracking down a vector version of the artwork if possible. Otherwise, try to get the highest resolution version of the artwork possible.
