Convert AVIF Images to ICO Format

AVIF (AV1 Image File Format) provides high compression efficiency and full alpha transparency, making it common on modern websites. However, Windows desktop shortcuts, application resources, and fallback /favicon.ico endpoints require the classic Microsoft ICO container. This tool converts any static or animated AVIF file (using its first frame) into a standard .ico file while preserving transparent pixels.

Choosing the Right Icon Size

  • 16×16 / 24×24 / 32×32: Compact sizes suited for browser favicons, address bars, and small UI lists.
  • 48×48 / 64×64 / 96×96: Desktop shortcut icons and high-DPI taskbar icons.
  • 128×128 / 192×192 / 256×256: High-resolution icons for large tile views in Windows Explorer.
  • Multi-size (16, 32, 48, 64, 128, 256): Bundles all six standard resolutions into a single .ico file so the operating system or browser can pick the best match automatically.
