Why convert JPEG to DDS?

Because JPEG files use lossy compression and 24-bit RGB, they are not ideal for Game textures and 3D graphics. Converting them to DDS (GPU-compressed, 32-bit) solves this. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. For most practical purposes, DDS simply removes a recurring headache.
