QDV files are also known as "Random Dot Software Graphics" and contain images that initially appear like a random collection of dots, forming an image only when you look at them from the right angle. Publishing such images used to be common in some printed media of the 1990s and continues to enjoy some popularity online.
The quick and simple way to handle your files is to get a quality piece of software, such as reaConverter. This software is extremely efficient in managing a wide range of batch conversions. As you will soon realize, reaConverter will help you avoid spending countless hours trying to figure out how to convert multiple QDV files as once.
