Aspect	AVIF (Source Format)	ICO (Target Format)
Format Overview	AVIF AV1 Image File Format A next-generation image format based on the AV1 video codec, developed by the Alliance for Open Media. AVIF achieves 50% better compression than JPEG and 20% better than WebP at equivalent quality, supporting HDR, wide color gamut, and film grain synthesis. It is rapidly gaining browser support and is the most efficient modern image format. Modern Lossy	ICO Windows Icon Microsoft's icon format for Windows applications and web favicons, capable of storing multiple image sizes and color depths in a single file. ICO files are essential for desktop icons, taskbar graphics, and browser tab favicons. Legacy Lossless
