When we work with companies to brand products and websites for them, we request vector logos - preferably in an .ai, .eps or .svg format. But what is a vector logo, and why do we want one?

Designers always prefer working with vector logos. The simplest reason is that vectors are extremely versatile and give us more freedom to resize as needed, while always maintaining the best quality possible for the treatment of your logo.

But what exactly is a vector logo?

A vector image is a file that uses coordinates to define the size and position of points, lines, curves and shapes to create an image. This means that no matter how the image is resized (whether it's a small logo on a business card, or a large one on a billboard), it always looks really clear and crisp. The most popular vector file formats are AI (Adobe Illustator format), EPS (Encapsulated Postscript) and the up and coming SVG (Scalable Vector Graphic) which can be used on the web.

This differs from a raster image (also known as a "bitmap" or "flattened" image), where each pixel is a specific defined color value. The biggest limitation of a flattened image is that it can't be made larger than the original size. Typical raster file formats are JPG, GIF, PNG, and BMP.
