Animated GIF Gallery Viewer solves Windows and macOS's biggest problem: viewing folders of animated GIFs. Instead of frozen thumbnails and one-at-a-time viewers, open any folder and watch your entire collection animate together in a scrollable grid. Pause at the exact frame you're looking at, zoom to 20x, step through frame-by-frame, and stay smooth across thousands of files. Completely private—files never leave your machine. No install, no account, no telemetry. Free, open source, and works in any modern browser.
