DNG是由Adobe系统公司开发的，名为Digital Negative，是一种高度兼容的开源原始图像格式，用于编辑、存储和传输RAW图像。
DNG格式是当前数字内容世界中的一个多媒体标准。而它显示了以下的优点和缺点。
DNG格式更灵活，因为它是一个开源文件，许多程序可以打开和编辑它。它们也比RAW文件小。然而，有时RAW文件由于其结构，在原始相机软件中的效果更好。
一些制造商尚未将该格式添加到他们的相机中，但其他制造商，如徕卡、哈苏和宾得，已经将其作为标准。
不，将任何格式转换为DNG不会影响图像质量，也不会有损失。它只是创建一个较小的文件，你可以在Adobe中更快地工作。
DNG文件可以被几个图像查看器打开，这包括Windows和MacOS照片查看器。虽然不是免费的，但Photoshop和Lightroom也支持这种格式。

DNG format guide
DNG is Adobe’s documented camera RAW container and can hold mosaiced sensor data, linear image data, previews, and metadata.
Published still-image routes use the deployed ImageMagick and Ghostscript toolchain, with dedicated workflows for animation, camera RAW rendering, SVG tracing, and selected modern formats where the generic path is not sufficient.
Render DNG to TIFF for editing or JPG for delivery when the recipient lacks RAW software.
The public upload limit is 1 GB. Convertr does not reduce dimensions, duration, resolution, or output quality merely to manage worker load.
PNG and TIFF are useful lossless working targets. JPG is lossy and removes transparency; WebP and AVIF may be lossy or lossless. Preserve source pixel dimensions unless resizing is intentional.
A rendered conversion bakes in decoding choices and cannot recreate untouched sensor data.
These links come from the active conversion catalog, not from a generic list of possible formats.
Choose one of these implemented routes; a listed extension is not a promise that every codec variant will decode.
Check that the file opens in its original application, is not encrypted or DRM-protected, and really matches its extension. A damaged header, unsupported internal codec, missing linked asset, or mislabeled file can fail even when DNG is generally supported. Try a different published target only when it fits your goal; changing the extension by hand does not convert the file.
