Before you start
Drop one or more Adobe DNG files; this format cannot be pasted as plain text.
Accepted: .dng · image/x-adobe-dng- Choose or drag one or more Adobe DNG files onto the drop zone.
- Confirm the detected format. Mixed-format batches are flagged before conversion.
- Select “Convert on this device.” Produces a readable JSON metadata report. Camera RAW pixel development is intentionally not attempted.
How this converter behaves
The browser decodes the image into pixels and re-encodes those pixels in the destination format.
What happens to your data?
The conversion engine runs in this browser tab. OmniCastConverter has no upload API and never sends your content, file name, or converted result to a server.
Fidelity and limitations
This route is classified as lossless. The converter preserves meaning and structure supported by both formats.
- This read-only route inspects available metadata. It does not demosaic, color-manage, edit, or export camera RAW pixels. Maker-note support varies by camera model.
