Why convert BMP to DDS?

BMP served its purpose well, but modern workflows increasingly favor DDS for Game textures and 3D graphics. The shift is worth making. 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 technical reasoning aside, the real-world result is fewer format-related issues.
