Wondering about PNG to DNG? Here's exactly what works, what doesn't, and why.
You can't create a genuine DNG from a finished PNG — but DNG conversion from camera RAW is real. Here's the full picture.
DNG is a RAW container built to hold the unprocessed data straight off a camera sensor. A PNG is an already-developed image — wrapping it in a DNG can't recreate the dynamic range or color depth it never kept.
Where DNG shines is converting a camera's own RAW (CR2, NEF, ARW…) into the open DNG format for archiving. That's a true conversion; turning a finished PNG into RAW is not.
DNG standardizes the proprietary RAW that cameras produce — these are the formats it replaces or wraps:
PNG is a lossless raster format with full transparency. It keeps every pixel intact, making it ideal for logos, icons, screenshots and graphics with sharp edges.
