Why convert DDS to AVIF?

Want faster load times and lower bandwidth costs? Switch from DDS to AVIF. The difference is dramatic: GPU-compressed vs lossy/lossless, 32-bit vs 12-bit HDR. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.

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