Why convert AVIF to HEIF?
Because AVIF files use lossy/lossless compression and 12-bit HDR, they are not ideal for Apple devices — efficient storage. Converting them to HEIF (lossy, 10-bit HDR) solves this. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches.
