Why convert CR2 to ICO?

If you work with CR2 regularly, you've probably hit compatibility walls. ICO was built for exactly this gap – Website favicons and app icons. Converting CR2 RAW images to ICO applies essential post-processing: white balance, demosaicing, and tone mapping. The result is a standard image ready for printing or further editing in any software. The conversion itself takes seconds — the benefits last much longer.
