What’s the difference between vector and bitmap images?

Here we tell you what’s the difference between vector, raster and bitmap images and what they are used for.

The main difference between vector and bitmap images is the way they are created. Bitmap images, also known as raster images, are made up of a grid of individual pixels. Photographs and many images created or edited in Photoshop are bitmap images. Their quality depends on the resolution, so enlarging a bitmap image too far can make it appear pixelated or blurred.

Vector graphics work differently. They are created using mathematical paths that define lines, curves and shapes rather than individual pixels. This means a vector logo or graphic can usually be enlarged or reduced to almost any size without losing quality. Vector artwork is therefore particularly useful for logos, icons, illustrations and other graphics that may need to be reproduced at different sizes.

For commercial print, knowing whether your artwork is vector or bitmap can make a significant difference to the final result. A high-resolution bitmap can produce excellent results, while low-resolution images may become soft or pixelated when printed. Vector artwork remains sharp and clean at any size.
