Frames: Use PNG/JPG/GIF. Name sequentially (e.g., 001.png, 002.png) for natural order.
Delay: Time per frame in milliseconds. 80-120 ms looks smooth; 33-50 ms is fast.
Loop count: 0 = loop forever; otherwise number of repeats.
Resize: If both W and H are set, images are fit proportionally inside that box.
Colors: Palette size (2-256). Fewer colors = smaller file. Try 32-64 for flat UI; 128-256 for photos.
Dithering: Helps gradients at low color counts; can add a grainy look.
Optimize: Frames are optimized and metadata stripped to reduce size.
Notes & tips
Large sources → large GIFs. For "sticker" style, consider 480-720 px.
Uploading an animated GIF as a frame uses only its first frame.
Color banding? Increase colors or enable dithering.
Choppy playback on some platforms? Try 100-120 ms instead of very low delays.
