Automatic Conversion from PDF to JPG

Universal Document Converter allows saving any type of a document as a PDF, JPEG, TIFF, or PNG image file. Software developers can benefit from the Universal Document Converter resources using the COM-interface with Adobe Acrobat as COM-server for converting PDF to JPG.
