Easiest way would be to take a screen shot of it. Just pull it up on screen so it looks the way you want it to appear. Press the PrintScreen key on your keyboard. Past the image (which is now in the Windows Clipboard) into any image editor and crop it the way you like. Save it as a jpg or bmp. Voilà!

Alternately you could use HTML and embed the PDF within an HTML page--and then display that HTML rather than an image. This might be easier if you have many PDFs because you would not have to convert them all.
