The DNG pixels are decoded and written using JPG compression and color capabilities.
- What is preserved
- Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
- What may be lost
- Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when JPG supports them.
- Codec and quality implications
- JPG uses lossy compression. A higher quality or bitrate can reduce new artifacts, but it cannot restore detail already missing from the DNG source.
- Realistic limitations
- Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.
