You can convert a PDF to a JPEG file using software included with Windows Vista and Windows 7. The drawback to doing this is that you lose image quality during the conversion. Other methods, which may give you more or less quality loss, include online and downloadable file converters.
Convert PDFs to PDF/X, PDF/A, or PDF/E. You can validate PDF content against PDF/X, PDF/A, PDF/VT or PDF/E criteria. You can also save a copy of the PDF as PDF/X, PDF/A, or PDF/E, provided it complies with the specified requirements. For example, under certain circumstances, an ICC profile that describes the destination device is required for PDF/X-1a, PDF/X-3, and PDF/X-4 compliance.
