Why convert PDF to DNG?
Because PDF files use mixed compression and 32-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.
