I see there is a transform function to generate a thumbnail version, but it only work for upload file with image type, is there any way I can upload PDF/docx file and can get the thumbnail of the first page of the document?

Yes - you can use any bash executable in your transform function. I'm not sure which command line utility would convert PDF to Image, but if you have one you can set it up as described in https://github.com/stavro/arc#complex-transformations
