Software to easily batch convert images in a post-editing phase.
Allows one to convert the file format of images, their dimensions, their contrast, and their brightness; it also allows one to specify that the format that originates the smaller file-size is the one that is to be output.
Opens images of type bmp, jpeg, png, and tiff, whether or not they are embedded in a data uri (a.k.a. data uri scheme or datauri scheme).
The program is batch-based, meaning that as soon as the settings are chosen they can be applied to as many files as you wish - you just have to let it process all of them.
Last but not least, the program has been created to be portable, thus, it does not require any installation at all and, as so, can be executed from a pen-drive.
