There are two kinds of computer graphics - raster (composed of pixels) and vector (composed of paths). Raster images are more commonly called bitmap images.

A bitmap image uses a grid of individual pixels where each pixel can be a different color or shade. Bitmaps are composed of pixels.

Vector graphics use mathematical relationships between points and the paths connecting them to describe an image. Vector graphics are composed of paths.

Vector drawings can be scalable to any size without any loss in quality. This makes them ideal for company logo's or other objects that have to be resized frequently.
I can convert your logo from a raster or (bitmap) image to a vector illustration. Your logo will be completely redrawn using the smallest amount of points possible keeping the design to a very small file size.

Bitmap images require higher resolutions and anti-aliasing for a smooth appearance. Vector-based graphics on the other hand are mathematically described and appear smooth at any size or resolution.

Bitmaps are best used for photographs and images with subtle shading. Graphics best suited for the vector format are page layout, type, line art or illustrations.

If you want me to convert your existing logo into a Vector Graphic I can do this usually for just £20 for most logos but may be more for complicated designs.

Just Email your existing logo as a jpg and I'll get back to you with a quote.
