What Are Vector Graphics (+7 Best Free Vector Graphic Software in 2019)

October 17, 2018

We’ve all seen the trope on a crime TV show — a detective reviews a grainy image of a suspect and asks the station’s tech wiz to enhance it.

There’s a reason the image never blows up clearly. Sure, part of the reason is for TV drama. But more importantly, because the image is not made of vector graphics.

Vector vs. raster graphics

To understand vector graphics, we must understand the two most common graphic design image file formats: raster and vector.

Raster format graphics (also known as bitmaps) are built using pixels. The term bitmap was derived from the fact that images in that format are literal maps of bits (or pixels) that are arranged in a specific layout.

A certain number of pixels construct raster graphics. Vector images, conversely, are constructed with mathematical equations as opposed to pixels. Let’s take a closer look at vector graphics, as well as the different use cases for each file format.

What are vector graphics?

Sure, vector graphics are math equations, but what does that mean? A vector graphic is an image constructed using mathematical equations or basic geometric elements such as points, lines and shapes. In computer graphics, these shapes and figures are called primitives because they are the most basic figures to which a shape can be broken down. They can be combined to create more complex figures using graphics software.

Vector format graphics are primarily used as source files for hard-edged graphics, logos and illustrations. This format is typically leveraged to create simpler images that will be scaled up or down, depending on the use case. Vector files must be converted to raster for use on the web or to be printed, typically in a .JPG or .PNG format.

Vector graphic file types

So many file formats exist in the business sphere; it’s easy to get confused over which is which. There are four common vector file types: .AI, .EPS, .PDF and .SVG. Let’s take a look at what each vector format means:

.AI (Adobe Illustrator):

A proprietary Adobe Illustrator file type that can only be created or edited with Adobe Illustrator. These files are made up of vector graphics contained in a single page. These files have restricted and compact syntax.

Best used for: Logos, graphics and illustrations

.EPS (Encapsulated PostScript):

A vector and raster (bitmaps) file that may contain graphics, illustrations and text. .ESP files may also included an embedded preview image in a bitmap format. These kinds of files support several different kinds of drawing platforms.

Best used for: Saving and transmitting art between different file formats and graphics editors

.SVG (Scalable Vector Graphic):

A vector image format that supports interactivity and animation, defined by XML text files. Scalable vector graphics were developed by the World Wide Web Consortium (W3C) starting in 1998. SVG allows three types of graphics: vector, bitmaps and text.

Best used for: Interactive graphics, which can be easily compressed (without loss of quality) because they are built of repeated text fragments

.PDF (Portable Document Format):

.PDF is a file format that is used to present documents filled with text and images. PDF files contain all the information necessary to render the document in its entirety, complete with bitmaps, vector graphics, text and interactive layouts.

Best used for: Text-rich documents that may contain interactive forms

What are raster graphics?

Raster graphics are pixel-based and have a finite number of pixels; that number is determined by the image resolution. The file is composed of data detailing the color of each pixel.

There are four common raster file types: .JPG, .GIF, .PNG and .TIF. Every raster image file contains the DPI (dots per inch) or PPI (pixels per inch) of the graphic. These numbers give the exact pixel count per respective file and an idea of the image quality.

Why vector graphics over raster?

Deciding between vector graphics and raster graphics really depends on the use case. The basic rule of thumb is that vector graphics are better for simpler, scalable images, while raster graphics software is better for photo editing and digital paintings.

A key benefit of creating vector graphics art is the ability to resize images without any loss in quality. Vector images are simply mathematical formulas, so it doesn’t matter if the image is blown up to 100 times its original size; the quality remains the same. Frequent resizing of images is easy to do with vector images because they are scalable up or down with little effort. Raster graphics, on the other hand, will delete data (in the form of pixels) if they are scaled down, which increases the blurriness of the image significantly if it is scaled back up.

The versatility of vector graphics is their main draw, and simple image manipulation is easy to do. Vector graphics are also fantastic for printing, as the creator can save an image in outlines and send it to the printer. This means that the shape will keep its integrity through transmission and printing.

What are the benefits of vector graphics?

One file format does not fit all. In some cases, vector file formats may not be right for your needs. But if they are, here are some benefits to using vector graphics in your work:

  • Vector file formats require less image space. Vector graphics are composed of simple gradients and flat colors. That means they require less disk space.
  • Vector graphics are easily scalable. Because of the way they are constructed, vector graphics can be scaled indefinitely. They will not lose their quality, as they are not composed of pixels.
  • Vector graphics are easy to modify. Many of these file formats are made up of a ASCII-format data, which means they are easy to modify. Elements can be added, removed or changed within vector graphics without impacting other objects in the image.
