Convert Images to RAW (DNG)
Turn any image into a DNG, the open RAW format every RAW editor reads. Everything happens on your device: nothing is uploaded, and there's no limit.
Your images are processed in this browser tab and never uploaded.
Why convert images to RAW (DNG)?
A JPG, PNG or HEIC opens in Lightroom as a finished image, with less room to push exposure and white balance. A DNG opens as a raw file, so you get the full raw controls and 16-bit processing: the same workflow you use for camera RAW files.
DNG is an open standard, so one file works in Lightroom, Lightroom Mobile, Camera Raw, Capture One, darktable and RawTherapee.
What to expect
- Honest note: your image is already a processed photo, so the DNG can't bring back detail that was never saved (blown highlights stay blown). What you gain is a raw workflow: 16-bit linear data, white balance and exposure controls that behave like raw, and no further quality loss while you edit.
- The DNG is uncompressed 16-bit, so it's large: about 6 MB per megapixel (a 12 MP photo becomes about 72 MB).
- Colours are tagged as sRGB with a D65 white point, so the photo opens looking like the original, with white balance set to As Shot.
- Transparent areas become white, because RAW files have no transparency.

Frequently asked questions
How do I convert an image to RAW?
Drop your images into the box above, press Convert and download the .dng files (or all of them as a ZIP). Open them in Lightroom, Camera Raw or darktable like any RAW file.
Is a DNG a real RAW file?
Yes. DNG is Adobe's open RAW format, read by every major RAW editor. This converter makes a linear DNG (16-bit RGB), the same kind Lightroom itself creates when it merges HDR photos or panoramas.
Will converting to RAW improve the quality?
No converter can. The image was already processed and compressed, and the DNG keeps exactly that image. It gives you raw-style editing with more headroom, not new detail.
Why not CR2, NEF or ARW?
Those are camera makers' own formats, tied to a specific camera's sensor, so no tool can create them from a photo. DNG is the universal RAW format every editor understands.
Are my files uploaded anywhere?
No. The conversion runs entirely in your browser on your own device. Nothing is sent to a server.
Does it work on iPhone and Android?
Yes, in Safari, Chrome, Firefox and Edge. On a phone, save the DNG to Files (or Downloads) and open it in Lightroom Mobile.
