this is not a PDF application, It is not a application to upload files to forums posts , they are extra's, It a media uploader application allowing you to upload media share it, make it private, crop your images, only allow certain members to view your uploads, and yes it allows you to embed your uploads into the editors including PDF's, IPS uploader does not allow PDF's to be uploaded as a pdf file on the editor, they rename it and remove the pdf extension removing the ability for it to be embedded and only downloaded
