Subject: Question about PDF Image Extraction Wizard
Date: Fri, 21 Apr 2006 20:33:49 +0200Hi,
PDF files can store images in both jpg and lossless format (usually both
depending on the type of image). It is up to the PDF creator software to
decide which format to use. PDF Wiz will extract all images in the format
they are stored inside the file. It does not recompress any images.
