Before you convert VSI to PDF

PDF is a page format, so each VSI image is placed on a page rather than converted into something else. Two settings decide how the result looks: the DPI, which fixes how large the image sits on the page, and whether a batch becomes one file per image or a single merged document. reaConverter can do either.
