How DDS to STL works
The raster path requests only the first decoded DDS image (frame index 0, one frame); there is no texture-face or mip-level selector. The resulting PNG pixels are used as an image, not as material or normal-map instructions. A normal map’s RGB channels do not directly describe printable height. Export a deliberate grayscale heightmap from the source tool when relief is intended, then compare the preview. Geometry sampling is limited to 512 points along the longest edge.
Compatibility and limitations
Layers and animation are not preserved. HDR images become display-range pixels; color is not stored in standard STL. This creates a relief or extrusion, not a reconstruction of hidden surfaces.
Get a more reliable result
Start with a clean source, choose dimensions appropriate to the intended use, and inspect the exported file. A successful conversion does not guarantee printability or automatic mesh repair. Read our detailed workflow guide for the decisions that matter.
Processing limits
Raster images: 20 MB and 24 million pixels. SVG: 2 MB. Image sampling is up to 512 points on the longest edge. Width 10–300 mm, proportional height 1–600 mm, depth 0.2–20 mm, relief base 0.5–10 mm.
One file at a time. Processing stops after 90 seconds. Files remain in browser memory, and no conversion upload is performed. Replacing a file clears the previous result. Closing the tab releases its working data.
Questions about DDS to STL
What information changes during conversion?
The output contains sampled geometry from the first decoded image. DDS material behavior, texture-face selection, mipmaps and normal-map shading are not reproduced as STL features. Prepare an intentional grayscale source rather than expecting a texture map to reconstruct an object.
How do I inspect the output?
Open STL output in the STL viewer, then verify the scale and geometry in your slicer. OBJ output can be checked in a mesh application.
