Why convert PNG to ICO?
Both PNG and ICO use lossless compression, so the conversion mainly changes compatibility, not quality. The main reason to convert PNG to ICO is compatibility: ICO opens in every browser, image viewer and design tool without a plugin, while PNG doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, ICO is usually the safer target.

ICO is windows icon container format. We use the highest-quality encoder settings by default so visual or data loss is minimized.
