Convert PDF files into pictures (JPG, BMP etc...) or into PDF files with only one picture of the content per page. This way nobody can modify your pdf files because there is no text information. It is like you would printout the pdf file, scan it.

Converts image formats such as TIF, JPG, GIF, PNG, BMP, WMF and PCX into PDF format. You can preview images and set the page order. It can operate independently of Adobe Acrobat and has faster processing speed.
