Why convert ICO to AVIF?
If you work with ICO regularly, you've probably hit compatibility walls. AVIF was built for exactly this gap – Next-gen web images — superior compression. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. Once you see the size or compatibility difference, going back rarely makes sense.
