Why convert HEIF to AVIF?
HEIF served its purpose well, but modern workflows increasingly favor AVIF for Next-gen web images — superior compression. The shift is worth making. 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 short, this is less about one format being 'better' and more about matching the tool to the job.
