ICO vs AVIF: Technical Breakdown
ICO vs AVIF: The definitive technical comparison. ICO (Microsoft Icon) is known for an image file format for computer icons in microsoft windows. it can contain one or more small images at multiple sizes and color depths. However, its architecture ico files are containers that can store multiple images with different resolutions and color depths (often bmp or png encoded). this allows the os to select the appropriate icon size for display without scaling artifacts. In contrast, AVIF is the industry standard for next-gen web delivery, hdr photography. AVIF utilizes the advanced AV1 video codec for image compression, achieving superior efficiency. It supports 10/12-bit color depth, High Dynamic Range (HDR), and Wide Color Gamut (WCG), technically outperforming legacy JPEG encoders. Converting ICO to AVIF optimizes your workflow for specific performance targets.
ICO (Microsoft Icon): An image file format for computer icons in Microsoft Windows. It can contain one or more small images at multiple sizes and color depths.
AVIF (AV1 Image File Format): AVIF (AV1 Image File Format) represents a quantum leap in web image compression. Derived from the AV1 video codec, it delivers smaller, higher-quality images than any predecessor.
