PDF images When we scan documents with the scanner in the office or on the multifunction machine at home, we will often find ourselves with various images of the document, available in JPG format. This format is optimized for images and is not very suitable for sharing important documents. And if we wanted to convert one or more images into a PDF document, definitely more comfortable to read and share?
Once this type of conversion could be very difficult to obtain, instead of today we find numerous sites and free programs to convert images to PDF. In this guide, we will show you the free sites where you can convert a series of images into a single downloadable PDF and, for those who are more attentive to privacy, we will also report free programs that can be installed on Windows to achieve the same result without an Internet connection.
