A vector image is composed of shapes and/or type created by movable points and segments that area either filled and/or outlined. This format allows the shapes to be scaled without loss of image quality.
Vector files are better suited for text based images and/or shape based graphics such as company logos and non photo realistic graphics.
A raster image is composed of coloured pixels arranged horizontally and vertically. This format allows the reproduction of photo based images.
Raster files are better suited for full color or black and white photo realistic images with minimal to no text.
The quality and detail of a raster image is based on it’s size and resolution. The resolution is the measure of horizontal and vertical pixels. The higher the resolution the more pixels the image has to reproduce detail and color.

PDF is a file format that has captured all the elements of a printed document as an electronic image that you can view, edit, navigate, print, or send to another electronic device. PDF files are created using Adobe Acrobat, Acrobat Capture, design applications such as Adobe Illustrator & Photoshop, or similar products. PDFs may contain both vector and raster information, but those details are not available to the viewer without compatible software to view those elements.
