Looking to convert FITS to DNG? Here's the honest answer — and what works instead.
Turn your file into a share-worthy AI Effect — one tap, no prompts.
FITS (Flexible Image Transport System) is the standard format of astronomy, storing telescope and scientific image data with extensive metadata headers.
FITS opens in astronomy software like SAOImage DS9, FITS Liberator and Astropy; convert to PNG/TIFF to view normally.
DNG is Adobe’s open, universal raw format. It stores unprocessed sensor data in a standardised container any modern editor can open — ideal for archiving photos.
DNG opens in Lightroom, Photoshop, Camera Raw and most pro photo editors.
Not meaningfully. DNG holds raw sensor data, which a finished FITS doesn't contain. DNG conversion makes sense from a camera's own RAW files, not from a processed FITS.
DNG (Adobe Digital Negative) is an open, royalty-free RAW format. It stores unprocessed sensor data in a standardized container any modern editor can open — ideal for archiving photos long-term.
DNG isn't higher quality — it's more universal and future-proof. Many photographers convert their proprietary camera RAW to DNG so files stay openable for decades.
FITS converts cleanly to JPG, PNG, TIFF and WEBP right now — free and unlimited.
