Why convert PDF to DNG?

If you work with PDF regularly, you've probably hit compatibility walls. DNG was built for exactly this gap – Universal RAW — open standard by Adobe. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. This is one of those changes that pays for itself almost immediately.
