Why is my converted ICNS file larger than the original AVIF?

This is expected. AVIF uses lossy compression for smaller files. ICNS preserves data losslessly, resulting in larger but higher-fidelity files.

What browsers are supported?

Chrome, Firefox, Safari and Edge (all recent versions). Any browser supporting WebAssembly will work.
