Convert 3DS to PLY
Free 3DS to PLY converter that runs in your browser. See real dimensions before you download.
How to convert 3DS to PLY
- Drop your 3DS file (with its textures, if separate) onto the converter — it opens in your browser, nothing is uploaded.
- Check the preview and the dimensions in mm; fix units or the up axis in “Units & orientation” if the size or orientation looks wrong.
- Choose PLY as the output and click Convert. Several files download as one ZIP.

About 3DS files
The .3ds format came from 3D Studio for DOS, released by Yost Group in 1990 and later acquired by Autodesk, which turned into 3ds Max. The file is binary and organised as nested chunks, each with an ID and a length, so a reader can skip chunks it does not understand. It stores triangle meshes, materials, lights, cameras and keyframe data. Its age shows in its limits: each mesh can hold at most 65,535 vertices and 65,535 faces because counts are 16-bit, object names are restricted to 8.3-style short names in practice, and texture file names are short as well. It also has no unit field. Despite that, thousands of free models from the 1990s and 2000s were published as 3DS, and many converters, viewers and game tools still read it. Modern 3ds Max saves in its own .max format and exports FBX.
About PLY files
PLY was developed in the mid-1990s by Greg Turk and colleagues at the Stanford Graphics Lab to store data from 3D scanners, and the Stanford Bunny and Happy Buddha models made it famous. A PLY file starts with a text header that declares elements, such as vertex and face, and the properties each element has. The body then follows in ASCII, binary little-endian or binary big-endian. Because properties are declared in the header, a file can carry any extra per-vertex data: normals, colour channels, intensity, confidence or custom scalars. This flexibility made PLY a standard output for scanners, depth cameras, photogrammetry and point-cloud tools. It can store a point cloud with no faces at all, or a polygon mesh. It does not define units or a scene structure.
3D printing notes
A 3DS model is only ever a starting point for printing. Slicers do not read it, and the files typically come from the game or visualisation era: low-poly meshes, split into many objects because of the vertex cap, with open seams between them. Those seams and overlapping parts need cleanup before they behave as a printable solid. The format records no unit, so check the size against what the model should be and rescale when needed. MeshShift reads 3DS in the browser, shows the dimensions, and converts to STL, 3MF, OBJ or GLB. Use the print check to find loose parts and holes and to rebuild one closed solid. MeshShift does not write 3DS.
Frequently asked questions
Is this 3DS to PLY converter free and private?
Yes. The conversion runs in your browser with JavaScript and WebAssembly, so your 3DS file is never uploaded to a server. There is no sign-up, no watermark and no daily limit; very large files are limited only by your device's memory.
Why are 3DS models limited in size?
The format stores vertex and face counts as 16-bit numbers, so a single mesh cannot exceed 65,535 of either. Larger models are split across several meshes. That cap came from the DOS-era software the format was built for.
Does PLY store colour?
Yes, usually as red, green and blue values attached to each vertex, not as a texture image. Colours are smooth across triangles, which suits scans. Many slicers ignore vertex colour, so use 3MF or another format if you need to preserve it for printing.
