The PDFin (formerly pdf2AutoCAD) Trial is free. You can download it either from Autodesk or directly from us. The links are below. Please note that the Trial version is fully functioning but each file will be stamped with a watermark. It should not get in the way of seeing whether your file opened correctly. If you do find it intrusive, just let us know and we will convert a test file for you without the watermark at no charge. This stamp is disabled when a full license is purchased.
