GifLoop vs Gifski

GifLoop is an iOS app for creating and editing animated GIFs, with projects that can start from photos, camera captures, video frames, or a blank canvas. Its tools include filters, text, drawing, onion skinning, glitch and jitter effects, and background removal. Creators can choose among seven loop modes, including ping-pong, random, fade loop, and play-once; per-frame timing is available on Pro. Free exports GIF and MP4, while Pro adds MOV, Live Photo, and frame strip. The custom Swift encoder offers controls for palette, dithering, lossy compression, file-size targets, and resolution. Free is free and permits up to 15 frames per project; GifLoop Pro is $1.99, paid once as a one-time purchase. The app requires iOS 17 or later and runs on iPhone and iPad. The maker says processing stays on-device and creative content is not uploaded to its servers; the editor and all five export formats work offline.

Gifski is a GIF encoder that turns video clips into smooth animations. It uses pngquant palettes and temporal dithering to produce frames with thousands of colors, alongside lossy LZW compression, temporal smoothing, and denoising. Users can resize animations and adjust compression to fit upload size limits. Quality is prioritized over small output by default; reducing dimensions, frame rate, or quality can make GIFs smaller. The site links to a free Windows graphical app and a macOS app, while command-line binaries are available for Linux, macOS, and Windows. The command-line workflow converts video through PNG frames, so ffmpeg may be needed to extract them. The macOS app includes trimming, cropping, dimension and speed controls, preview, looping and bounce options, and sharing integrations. It converts video rather than creating GIFs from added text or other elements, and it does not support QuickTime Animation. The library is open source for free software use; closed-source apps or services require a commercial license.
