AVIF (AV1 Image File Format) uses lossy or lossless encoding and is best for next-gen web images — royalty-free format with better compression than WebP and JPEG. ICO (Windows Icon) uses lossless (multiple sizes) encoding and excels at favicons and app icons — standard format for website bookmarks and Windows application icons. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
The output ICO typically includes 16x16, 32x32, 48x48, and 256x256 pixel variants. This covers favicon, taskbar, and desktop icon requirements across Windows.
ICO uses embedded bitmaps (BMP/PNG). The AVIF is rendered at each required size and embedded as PNG frames in the ICO container.
