Why convert DDS to ICO?

Have you ever tried using a DDS image on a platform that doesn't support it? That's frustrating. By converting to ICO, you get a universally compatible lossless file that works everywhere. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. The gap becomes more obvious the more DDS files you're managing at once.

This format requires a WebAssembly decoder — allow a moment for library loading
