Why convert TIFF to DNG?

Because TIFF files use lossless compression and 48-bit, they are not ideal for Universal RAW — open standard by Adobe. Converting them to DNG (lossless RAW, 16-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.
