ICO to AVIF Conversion
ICO is a file format specifically designed for computer icons in Microsoft Windows. An ICO file can contain multiple images at different sizes and color depths, allowing the icon to scale appropriately across the interface.
AVIF is a modern image format derived from the AV1 video codec. It offers excellent compression efficiency and high image quality, often outperforming WebP and JPEG. It supports HDR and wide color gamut, making it a future-proof choice for web images.
Frequently Asked Questions
ICO's Windows-specific multi-resolution format is designed exclusively for icon display, not modern web image delivery. Converting to AVIF extracts cutting-edge web-optimized images with superior compression.
Converting ICO to AVIF creates a modern image with next-generation compression - significantly smaller than PNG (30-50% reduction) while preserving transparency and quality. Perfect for using icon artwork in cutting-edge web applications, achieving maximum performance through smallest possible file sizes. Browser support growing (Chrome 85+, Firefox 93+, Safari 16+) - ideal for progressive enhancement strategies. Extract the largest embedded ICO size for best results before AVIF's superior compression applies. Note: this conversion makes most sense when web performance is critical; for broader compatibility, convert to PNG or WebP instead.
