What is gifski?

Gifski is a Mac app that converts your videos into animated GIFs, and it does so with notably higher visual quality than most tools. If you've ever made a GIF from a video and noticed it looked muddy, grainy, or washed out, this app aims to fix that. It supports common video formats like MP4 and MOV files, so you can take a clip straight from your phone or camera and turn it into a GIF that can use thousands of colors per frame instead of the limited palette most GIFs are stuck with. Under the hood, the app relies on an encoder (the engine that processes the video) that uses some clever techniques to preserve color and detail. Instead of simply shrinking the video down and guessing at colors frame by frame, it looks across multiple frames to build a smarter color palette. It also uses a technique called temporal dithering, which helps smooth out color transitions so the final GIF looks much closer to the original video than a standard converter would produce. The primary audience is anyone who regularly shares GIFs and cares about them looking good, designers creating mockups for presentations, marketers making product demos for social media, or even casual users who just want a high-quality clip for a blog post or message. The app also integrates directly into macOS, so you can right-click a compatible video file in Finder and convert it to a GIF from the Services menu without even opening the app separately. The project itself is a native macOS app built in Swift, but it actually bridges two different programming worlds: the user interface is built with Swift and Apple's tools, while the core encoding engine that does the heavy lifting is written in Rust, a language known for performance. This combination lets the app feel like a natural Mac application while benefiting from a fast, efficient conversion engine under the surface. The project is open source, though the maintainers note they are not accepting community translations for the interface.
