Creates one square icon. The image is fitted inside it without stretching.
The target can store an alpha channel, but converting an opaque image does not create transparent areas. Removing a background is a separate editing step.
ICO compression depends on the embedded image payload. Multiple sizes are alternatives, not animation frames; transparency handling differs between old masks and alpha-capable images. The output uses the implemented still-image encoder; file size depends on the pixels and format.
