Quality & Compatibility Strategy
ICO to AVIF works best when you start near quality 45-62 and validate with real assets.
Transparency can be preserved through this conversion route. AVIF can hold animation, but converting static ICO files will still produce static output. Expect notably smaller files in most real-world images.
Useful for next generation compression that often beats WebP in file size
