Convert videos to high-quality GIFs on your Mac

This is a macOS app for the gifski encoder, which converts videos to GIF animations using pngquant's fancy features for efficient cross-frame palettes and temporal dithering. It produces animated GIFs that use thousands of colors per frame.

Gifski supports all the video formats that macOS supports (.mp4 or .mov with H264, HEVC, ProRes, etc). The QuickTime Animation format is not supported. Use ProRes 4444 XQ instead. It's more efficient, more widely supported, and like QuickTime Animation, it also supports alpha channel.

Requires macOS 10.13 or later.



Change GIF dimensions with the keyboard

In the width/height input fields in the save panel, press the arrow up/down keys to change the value by 1. Hold the Option key meanwhile to change it by 10.

System service

Gifski includes a system service that lets you quickly convert a video to GIF from the Services menu in any app that provides a compatible video file.


Building from source

To build the app in Xcode, you need to have Rust and GCC 8 installed first:

curl -sSf | sh
brew install gcc@8 SwiftLint
xcode-select --install


Can I contribute localizations?

No, we're not interested in localizing the app.

Can you support Windows/Linux?

No, but there's a cross-platform command-line tool available.
