ConvertWhat happens when you convert SVG to ICNS
- SVG is vector: choose an output size (1× to 8×) and the image is drawn sharply at that size.
- The ICNS file contains every size macOS uses, from 16×16 to 1024×1024 (Retina), stored as PNG.
- For the sharpest icon, start with a square image of at least 1024×1024. Other shapes are centered with transparent padding.
- Transparency is kept.
