You are probably more familiar with .jpg images, like those you would get from your digital camera. If you ever try to zoom in very close, you will notice that the image becomes blurry and the colors turn into little squares or dots. But this king of thing will never happen to vector images. So what is a vector image and what are the characteristics?
What is Vector Image?
A vector image is an image that results from a combination of points and lines with a mathematical formula, thus forming a polygon depicting a particular image object. The location of a vector image is called control points or nodes, where the location of each point has a definite position based on the x and y axis. In a vector image, each line or point can be added with various attributes, such as shape, line thickness, curves, line color, and fill color.
Vector Image Format
The format for Vector images itself varies, including:
- CDR (format from Corel Draw)
- AI (format from Adobe Illustration)

Characteristics of Vector Images
By using these characteristics below, you can identify a vector image easily. The characteristics of vector image are:
- Vector images are formed from a combination of individual objects consisting of points, lines and colors.
- Image size does not affect the quality of the displayed image, because it does not depend on image resolution.
- Has a relatively small size
- It is scalable so it won’t break when the image is enlarged
- The resulting image display is less real and natural, so it cannot be used to produce realistic photo images.
- When displayed to the monitor screen requires a longer process.
Pros of Vector Images
Vector images can have some advantages than other image format, such as:
- The storage space used by drawing objects is more efficient.
- Can be printed at high resolution using a printer.
- Images can be resized to any size without fear of deterioration.
- Vector images are easier to edit.
Disadvantages of Vector Graphics
But, this type of format can also have disadvantages. If the image is converted to a bitmap, it cannot generate the main vector anymore and loses all of its vector characteristics.

In the world of graphic design, vector graphics are a big part in most printed or published materials. Logos should always have a vector format so those smooth lines and shapes produce the best quality for printed materials. You can use your vector logo blown up on a huge billboard or made smaller for small accessories by using vector format.
