About ICAT

The NVIDIA Image Comparison & Analysis Tool (ICAT) is a web-based application designed for fast, easy visual media comparisons without requiring professional editing software. It is built for users who need to evaluate differences between image or video versions, such as quality testers, content creators, and video editors.

ICAT lets users load up to four images or videos at once, with tools to align, trim, create loops, adjust playback speed, and zoom or pan to focus on specific details. It offers two core viewing modes: split-screen for synchronized side-by-side comparison of multiple files, and single-screen overlay for direct A/B comparisons with an adjustable reveal slider. A downloadable user guide is available for new users.
