Pre-configured for Twitter / X's limits. Target size: 15 MB · Recommended width: 640px.
Twitter allows GIFs up to 15 MB and up to 350 frames in length.
Twitter converts GIFs to MP4 for playback. The re-encoding can alter colors and sharpness slightly.
Keep the GIF under 15 MB, use 256 colors, and avoid extreme lossy compression. Twitter's re-encoding handles the rest.
