ImageVice 2.1 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The software is included in Audio & Video Tools. We recommend checking the downloaded files with any free antivirus. This software for Mac OS X is an intellectual property of BoxTop Software.
From the developer:
ImageVice can make GIF, PICT, BMP, and PNG (the most popular multimedia formats) images up to 70 percent smaller without sacrificing image quality. ImageVice color reduction technology uses a procedural method for removing space-variant system imperfection and neural modeling of the logarithmic response of the human visual system.
