Converting JPG to ICO does not create transparency by itself.
Converting JPG to ICO decodes the source image and writes a ICO output. Use this route when ICO is a better fit for compatibility, file size, editing, or delivery.
Quality behavior depends on ICO compression: depends.
Choose conversion targets based on ICO compression, transparency, animation, metadata, and compatibility requirements.
