Why convert JP2 to AVIF?

Think of AVIF as the format JP2 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. In practice, teams that make this switch rarely go back to JP2 for this use case.
