Why convert DIB to AVIF?

People often ask why bother converting DIB at all. The short answer: AVIF handles Next-gen web images — superior compression noticeably better. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. Think of it as future-proofing your files rather than just converting them.
