Why convert HEIC to DNG?
The main issue with HEIC is lack of browser support. Converting to DNG fixes this by providing broad compatibility across devices and software. 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 HEIC for this use case.
