PDF is widely used because it is stable, not easy to be altered. And because PDF supports cross-system operation, it can work in different systems, Windows, Unix, Mac OS and so on. However, if we don't need to make use of the whole PDF, instead, we just need several pages or the whole file is too large, that may result in problems. And we can't just extract several pages or delete the other pages because it is a PDF. In this case, we can convert the PDF to JPG, each page as an image.

This can be done very easily with vJupiter PDF to JPG Converter which is freeware to split PDF to images (*.jpg). This program is user-friendly and just takes several steps to complete the conversion: Add PDF or multiple PDFs to the file box, define DPI for the output JPGs, and then click «Convert» button to start conversion. Within minutes, the PDF will be split into separated JPG files.
