Tiff2PDF Pilot is a simple batch conversion utility that converts TIFF files (including multi-page images) to PDF. It allows you to set security settings for the generated PDF files as well as document information and page order. Rather expensive, considering that it only supports a single format, while most others PDF converters have no limit on formats they support.
