Mass Image Compressor

Mass Image Compressor is a Windows utility designed to reduce the size of image files occupying the disk by applying quick optimization methods. It comes packed with just a few intuitive options that can be easily figured out by users.
In addition to compressing your files, the application is also capable of converting them to JPEG or PNG.

Hassle-free installation and simple GUI

The setup procedure is brief and uneventful, since no special attention is required here. As for the interface, Mass Image Compressor adopts a single and classical window that does not contain visually striking elements.
One aspect that should be noted is that .NET Framework needs to be installed on your machine for the application to function correctly, but, on the whole, the setup procedure is relatively straightforward.

Optimize whole directories with photos

Batch processing is supported, meaning that you can work with entire folders of images to reduce the overall task duration. A directory can be pointed out with the help of the tree view.
It is possible to adjust the compression quality, set a fixed height and tweak it, as well as to save the new pictures as JPEG or PNG files to a user-defined directory. In addition, you can examine the modifications before applying them, as well as zoom in and out of the pictures. There are no other notable features provided by this software utility.
