DDS

No. DDS holds GPU-native block-compressed texture data that is not directly viewable by generic image tools, so a DAM needs a dedicated renderer or converter to generate a PNG-style preview.

No. Keep DDS as-is for game and 3D production pipelines, since re-encoding loses the GPU-specific block-compression tuning, such as DXT1-5 or BC4-7 from Direct3D 10 onward, chosen for that particular texture.

DDS carries essentially no descriptive metadata. Its header stores only technical parameters needed to decode the texture — width, height, mipmap count, the pixel format or FourCC code (DXT1-5, or BC4-7 from Direct3D 10 onward), and caps flags marking a cubemap or volume texture. There is no EXIF/IPTC/XMP block for title, keywords, creator, or usage rights, so a DAM must track that descriptive and rights metadata externally, in its own database record or sidecar file, rather than reading it from the asset itself.

Beyond the compressed pixel data itself, a DDS file bundles a full mipmap chain — successively half-sized versions of the texture used for distance-based level-of-detail — plus header fields describing dimensions, pitch, and caps flags that mark the surface as a cube map (six faces) or a volume texture. Files using Direct3D 10-era formats add a DX10 extended header specifying the exact DXGI pixel format and, since that extension, support for texture arrays as well.

Neither application reads DDS natively out of the box, so a DAM workflow needs a plugin layer. For Photoshop, NVIDIA and Intel each publish a DDS plugin that adds DDS to the format list in File > Open and File > Save As, exposing options for compression type (DXT1-5, BC4-7) and mipmap generation on export. GIMP takes a DDS import/export plugin that similarly registers the format with the standard file dialogs, letting an editor preview and re-save the texture without leaving the raster editor.

Microsoft's DirectXTex library ships command-line utilities — texconv for format conversion and mipmap regeneration, and texdiag for inspecting a file's header, pixel format, and DX10 extended-header fields — that handle DDS natively, since Microsoft maintains DDS as part of the DirectX toolchain. ImageMagick can also convert DDS to standard raster formats such as PNG or TIFF for browsing, provided its DDS delegate library is installed, though it does not expose the same level of DXT/BC compression-format detail as DirectXTex.

Microsoft introduced DDS in 2000 alongside DirectX 7.0, as a container that let real-time 3D applications — chiefly games — store textures pre-compressed into the DXTn block formats GPUs of that era could decode directly in hardware, avoiding CPU-side decompression at render time. The format was extended in later DirectX releases: DirectX 8.0 added volume-texture support, and Direct3D 10 introduced texture arrays along with the newer BC4-7 compression schemes, keeping DDS aligned with each generation's GPU capabilities.

No. It is an asset-pipeline format for real-time 3D rendering, not a photographic one, and a DAM cataloging game assets should classify and handle it differently from camera-derived raster images.
