Why convert HEIC to ARW?

Because HEIC files use lossy compression and 10-bit HDR, they are not ideal for Sony Alpha mirrorless photography. Converting them to ARW (lossless RAW, 14-bit per channel) 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.

Transparent areas will be filled with white background
