When not to convert GIF to ICO
- Skip ICO for the smallest share: lossless output stays large, so prefer a lossy target when sending GIF files.
- Still frames only: ICO cannot animate, so just the first frame of GIF carries over.
Limits
Starting point: GIF - 256-color animation with 1-bit transparency. Limited to 256 colors per frame, so gradients may band. Conversion rasterizes one size, so start from the largest entry. Export ICO from GIF at matched dimensions; every pixel maps across, so large sources stay large.
