How do I convert AVIF to ICNS step by step?

Upload your AVIF image, select ICNS as the output format, and choose a target size (512px is recommended). Click Convert, then download the resulting ICNS file. Our tool automatically generates all standard icon scales from the master image.

Why should I convert AVIF to ICNS instead of using another icon format?

ICNS is the native icon container for macOS, designed to store multiple scales for Finder, Dock, and app bundles. AVIF offers excellent photo compression but is not supported by the macOS Icon Composer. Converting AVIF to ICNS lets you use a modern compressed source while maintaining full macOS compatibility and crisp Retina output.

Does AVIF to ICNS conversion preserve transparency and color profiles?

Yes. The converter keeps the alpha channel intact and embeds the original ICC color profile into the ICNS file. It also generates the full set of required icon sizes (16x16, 32x32, 128x128, 256x256, 512x512, plus @2x variants) from the source pixels. The actual pixel data is not recompressed, so image quality is retained.
