Why convert HEIC to DDS?

Because HEIC files use lossy compression and 10-bit HDR, 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. The technical reasoning aside, the real-world result is fewer format-related issues.
