Image To PDF is a Windows application which can directly convert dozens of image formats, such as TIF, JPG, GIF, PNG, BMP, PSD, WMF, EMF, PDF, PCX, PIC and so on, into PDF format. Image To PDF can automatically clear and skew-correct B/W images by employing special techniques to insure high quality output after conversion. ImageToPDF can operate independently of Adobe Acrobat and has faster processing speed.
