The PDF Converter supports a large, and growing, number of file formats. For input as well as output.
Input file formats include most of the common file formats such as MS-Word, Excel, InfoPath, PowerPoint, HTML, MSG, Visio, AutoCAD and images.
As of version 6.0 it is possible to convert many of the supported files to formats other than PDF as well, e.g. InfoPath to Word or Excel, Excel to MS-Word, DOC to DOCX etc.
It is also possible to integrate third party converters in order to support more esoteric file formats such as PCL, XPS, HPGL, CGM etc. For details see this KB article.
As of version 7.2.1. it is possible to select a number of additional output formats, specifically TIFF, PNG, GIF, JPG, PS, BMP, PCL. The converter does not (yet) natively support these output formats, but support can be added using third party converters.
