AVIF vs ICO: Technical Breakdown
AVIF vs ICO: The definitive technical comparison. AVIF (AV1 Image File Format) is known for 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. However, its architecture 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. In contrast, ICO is the industry standard for favicons, desktop icons. 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. Converting AVIF to ICO optimizes your workflow for specific performance targets.
