Why convert DDS to AVIF?

Think of AVIF as the format DDS files graduate to once they need Next-gen web images — superior compression. 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 is one of those changes that pays for itself almost immediately.

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