It has excellent compression characteristics and has the nice feature that the user may specify what level of compression they desire, trading off fidelity for file size. One of the most widely-used image formats. They are also commonly used on the web to save bandwidth. They are best suited to photographs and other images where perfect accuracy is not important. These have smaller file sizes but do not store a perfect copy of the image. Some of the most common are: JPEG, PNG, GIF, BMP, and TIFF.īroadly speaking, they fall into two categories: Lossy formats The same is not true for raster images, since the color information of these images is stretched when scaled.There is a large number of different bitmap formats. That means images don't lose quality when they're scaled up or down, since the color polygons in a vector image will always maintain their shape. The geometry which comprises vector images is formulaic, making them resolution-independent. Since vector images use dynamic color sections instead of static squares, they provide perfect lines and crisp colors.

Vector graphics convey color using scalable color polygons. Raster images use square pixels (bits of color) to convey an image. Most images found online are raster images.

What Is a Vector Image?Ī vector image is a scalable image made up of values rather than pixels.

Here's how to convert an image to a vector using Adobe Illustrator. It's a quick and simple process and produces excellent results. When you've got a raster graphic that's too small for your needs, the solution is to convert the image to a vector, and you can do this in Adobe Illustrator.
