Fotosizer is a free tool for massively changing the resolution of image files stored on your computer's hard drive. The application offers a convenient and fast mechanism for changing the size of individual photos that we intend to share on the Internet or use for other private purposes. Operation of the program is simple.

Simply select any folder with photos that will be automatically added to the application after a while. Then we configure the appropriate size change settings, i.e. enter the width/height of the image and select the target directory where it will be saved.

After pressing the button that starts the process of compressing image files, the program will automatically change the resolution without any loss of quality. After loading graphic files into the application, we receive a detailed description of their parameters, from which we can read their current size, resolution and file format. In addition, Fotosizer has advanced configuration options, allowing you to select the output format (JPG, PNG, BMP, GIF, TIF) or use different effects (negative, black and white image).

There were also functions to change the rotation and quality of the graphic file.
