Vector vs. Raster – What’s the Difference?

How to tell if a file is Vector or Raster
Customers always ask. I have a logo, can you work with this? I ask what format is it? Is it raster or vector? The customer doesn’t know. How can you tell? The first way to tell is the file format. A vector file format is .ai, .pdf., .eps, and .svg. The customer has a jpeg file. That’s raster. A raster file can be .jpg, .tif, .png, or .bmp. But what’s the difference between these files?
Here are 2 different logos.
Can you see the difference? Not really? Let’s get even closer.
The one on the left looks a little blurry. Here’s a big picture of the raster logo.

Do you see the difference now? What are those little squares? What is a raster file? A raster file consists of individual pixels – usually a photo image, like a Adobe Photoshop file. When you zoom in really close, you can see the little pixels. Why is this a problem? Raster images cannot be enlarged, and if they are low resolution, your logo will be illegible. It will be hard to modify and to change the colors.
With a vector image, you can enlarge it 10 times, and it will still look the same. A vector file is usually created in Adobe Illustrator. With one click, the colors can be instantly changed. The logo can be added to any type of product easily- put it on a t-shirt, business card, or banner. The logo can be cut out on vinyl – make an instant window vinyl graphic! The possibilities are endless.
How is the logo vectorized?
I recreate using Adobe Illustrator by hand (I don’t use tracing programs or filters) Tracing programs are not 100% accurate, and can lead to jagged lines. I use the pen tool to recreate it, allowing for smooth, accurate detail. It does take more time to do it, but you will appreciate your final product. Do you need a file vectorized?
