Is this a full RAW convert like Lightroom or Adobe Camera Raw?

No. DNG is a TIFF-based RAW. This page copies the largest JPEG preview the camera (or phone) already baked into the file. White balance, sharpening, and highlight recovery stay as the camera processed them — there is no demosaic slider.

Which phones and cameras work?

Pixel Camera DNG, iPhone ProRAW `.dng`, and most Leica / Adobe DNG exports that include a preview. CR2, NEF, and ARW are different formats and are not converted here.

No. Parsing stays in this tab. Close the page to drop the file from memory. Max size is 80 MB.

Why did conversion fail?

Linear or studio DNGs sometimes omit a JPEG preview and store only mosaic sensor data. Those files need a desktop RAW developer. A JPEG renamed to `.dng` also fails the TIFF parser.

這個工具是什麼？

An in-browser DNG → JPG exporter for camera stills. Drop a .dng, wait while the page finds the largest embedded JPEG, then download .jpg. Nothing is sent to a server.

It is not HEIC conversion (use HEIC to JPG), not an image compressor (use Compress image), and not a full RAW develop.

常見用途

Share a Pixel Night Sight or Pro camera DNG in Slack, WhatsApp, or a CMS that only accepts JPEG
Open an iPhone ProRAW .dng on Windows without Adobe Camera Raw
Keep a quick reference JPG next to the archival DNG on disk

如何使用

Drag a .dng from Finder, Explorer, or your phone.
Wait for the preview (large 50 MP files can take a few seconds to scan).
Download JPG. The file never leaves the device.

範例

Input	Notes
Pixel Camera `*.dng`	Usually contains a large JPEG preview; output `*.jpg`.
iPhone ProRAW `.dng`	Same pipeline; the baked preview is camera-processed.
80 MB+ DNG	Rejected — export a smaller DNG or convert on desktop.
Linear DNG with no JPEG	Fails; there is no preview stream to copy.

實務上常見陷阱

Preview ≠ demosaic: exposure and color match the camera JPEG, not a Lightroom profile. A full RAW develop is not available in this browser tool.
Some studio / cinema DNGs store only mosaic tiles. If no JPEG is found, use a desktop converter.
We do not convert Canon CR2, Nikon NEF, or Sony ARW.
