A tiny Windows app that converts images to PDF doc with few seconds. The program is able to convert JPG, TIF, BMP, PNG, GIF, ICO, PSD, TIFF and JPEG to PDF documents. Besides converting every single JPEG image to PDF files normally, the converter also has an option to convert multiple JPG files to a single PDF file. That means you can make your own PDF photo album or PDF eBook.
