Camera raw conversion requires decoding, demosaicing, white balance, tone mapping, and encoder choices.
Converting 3FR 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.
