Why convert ICO to AI?

Introduced in 1985 by Microsoft, ICO was great for its time. But AI (created in 1987 by Adobe) offers vector compression and unlimited – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
