No, TotalDocConverterX can't be used to convert a multi-page PDF file to TIFF. According to the official information, you can convert a DOCUMENT (eg. Word, DOC, DOCX, DOCM, and TXT) to PDF, XLS, HTML, JPEG, TIFF, RTF, TXT and Unicode TXT formats. As you can see, it's using documents as input to convert them to the mentioned formats. You still have to use the current option in Classic ASP.
