PDFill & Image Writer is able to convert printable files into PDF or in an image format (JPG, PNG ..). It works as a virtual printer and all options can be set through its interface, before processing the file.
Using it, you can choose between different built-in profiles for PDF optimization, add user and owner password to prevent printing, editing etc., add metadata information, rotate or crop the file.
After you generate the PDF, you can access the PDFill PDF Tools menu to apply other actions (merge, split, rotate, add image/text watermark).
There are better competitors to make smaller PDFs. The size is important if you need to send files by email.
The program allows to add metadata and to set passwords to prevent the access or actions such as print, copy, modify.
The options are easy to use and you can add post-processing actions (send by email, merge, split ..), choose settings for custom quality of PDF. The program include another module to edit the generated PDF file, but these actions can be done after and not before creating the PDF (add watermark, merge etc).
Good as a simple conversion program, but for advanced options is annoying, at least at first use.
