How to open a 3DS file online

  1. Open the file

    Drop .3ds files with their texture images.

  2. Check size and orientation

    The model stands on the plate in millimetres. Switch to inches, or change the file units or up axis if it looks wrong.

  3. Run the checks

    Read the mesh check, pick your printer to see whether it fits, and use Measure (M) or Section (X) for a closer look.

  4. Save or convert

    Take a PNG screenshot, or save the model as STL, 3MF, OBJ, GLB, PLY or USDZ.

What you can check in 3DS files

  • Meshes, materials and textures
  • Size in mm or inches with selectable file units
  • Watertight check before printing
  • Section view and measuring
  • Save as STL, OBJ, 3MF or GLB

About 3DS files

3DS is the native format of the DOS-era Autodesk 3D Studio. Its 16-bit structure limits each mesh to 65,536 vertices and texture names to 8.3 characters, but large libraries of older models still ship as .3ds.

3DS stores no units, so the viewer reads the numbers as millimetres; change the file units if the size is off. Drop texture images with the .3ds to see them.

Tips for 3DS files

Upper-case textures

3DS texture names are often upper case (WOOD.JPG). The viewer matches names regardless of case.

Many small meshes

Big models are split into many meshes by the format's vertex limit. They are merged when you save as STL.

Modernize it

Save as GLB to keep the textures in one modern file.

3DS viewer FAQ

What opens a 3DS file?
3ds Max, Blender (with an add-on), many older tools, and this page, without installing anything.

Can I convert 3DS to STL?
Yes, with 3DS to STL or Save as STL here.

Why is my 3DS model the wrong size?
The format has no units. Set the file units in the sidebar, or scale it in your slicer.

Is the viewer free? Are there limits?
Free, with no sign-up, watermark or file limit. The practical limit is your device's memory: files of a few hundred MB open on most laptops.

Are my files uploaded anywhere?
No. Files are read by JavaScript and WebAssembly in your browser and never sent to PrintPal. Only the code is downloaded, and the STEP and IGES reader once, from a public CDN.
