About This Tool

3DS was a popular 3D model format in the 1990s, widely used in games and architectural visualization. Converting it to GLB gives you the modern standard for web, AR and 3D printing. Textures are automatically embedded into a single file, so you don't need to handle them separately.

Frequently Asked Questions

View all FAQs

What model features are preserved after conversion?

The conversion preserves geometry, material colors, texture maps, and object grouping. However, animations and some special effects from older 3DS files may not carry over. The output uses high-quality materials suitable for modern web display.

Why do 3DS models need to be converted to GLB?

3DS is an older format with limited support for model detail and materials (e.g., a single mesh cannot have too many polygons). GLB is a modern standard without such limitations, supports high-quality materials, and can be previewed directly in browsers and AR devices without plugins.

How can I ensure textures are embedded correctly?

Place the 3DS file and its referenced texture images (e.g., JPG, PNG) in the same folder. The converter will automatically recognize and embed them into the GLB. If textures are missing, the output may appear gray.

Can it handle 3DS files with multiple parts?

Yes. Each object is converted into a separate mesh in the GLB, preserving its own material for easy editing or splitting later.

Can the converted GLB be used directly in Unity or Unreal Engine?

Yes. GLB is natively supported by Unity, Unreal Engine, Blender, and browser-based viewers such as three.js, so the output can be dropped straight into game projects and web scenes without extra plugins.

3DS is an old format: what pitfalls should I watch out for?

3DS was designed in the 1990s, so files may carry inconsistent unit or axis conventions depending on the exporter. If the model appears rotated or scaled oddly in the preview, re-export it from your 3D software with consistent settings before converting.

About Configuration Options

General Settings

Up axis

Y-up

Determines the 'up' axis of the exported model. Different 3D software uses different conventions. Selecting the wrong system may cause the model to lie on its side.

  • Y-upRecommended: Convention used by OpenGL, Three.js, and most Web 3D engines. Choose this for models from web or game engines.
  • Z-up: Convention used by Blender (default), 3ds Max, and some CAD software. Try this if the model appears sideways.

Rotation X

0°-180° – 180°

Rotate the model around the X axis (degrees). Useful for correcting axis misalignment or print orientation.

Rotation Y

0°-180° – 180°

Rotate the model around the Y axis (degrees). Useful for correcting axis misalignment or print orientation.

Rotation Z

0°-180° – 180°

Rotate the model around the Z axis (degrees). Useful for correcting axis misalignment or print orientation.

Rotation Application

Root node transform

Choose how rotation is written to the exported model. Baking into vertices rewrites all vertex coordinates so every export format (including geometry-only formats such as STL and STEP) applies it consistently; root node transform keeps the original vertex coordinates, which is friendlier to animated or skinned models, but formats that ignore node transforms (such as STEP) won't apply the rotation.

  • Bake into vertices: Rotation is written into all vertex coordinates and applies consistently to every export format; geometry data is rewritten.
  • Root node transformRecommended: Rotation is written as a root node transform while vertex coordinates stay unchanged; better for skinned or animated models, but formats that ignore node transforms (such as STEP) won't apply it.

Format Information

Input format

Extension:
3ds
Full Name:
Autodesk 3ds Max (3DS)
Type:
3D Model
Format:
3DS
Tools:
Three.js、Blender
Open With:
Blender、View in 3DS Viewer
Description:
3DS is a file format created by Autodesk for early versions of 3ds Max, originating during the nascent stage of 3D graphics. It remains widely used in numerous legacy assets and asset libraries. It stores mesh, material, and basic texture information, offering a simple structure and good compatibility. Due to early specifications, 3DS has clear limitations: a relatively low vertex count cap, 8.3 short filename restrictions, and primitive animation and bone support. Consequently, it is rarely used as a primary format in modern workflows. When encountering 3DS files in old projects or material libraries, conversion to GLB or OBJ is typically required for continued use.

Notes:

  • 3DS is a legacy format limited to 8.3 texture filenames

Supported Features:

  • Real-time WebGL rendering
  • Orbit controls with rotate/pan/zoom
  • Wireframe and shaded display modes
  • Animation playback (if supported by format)

Output format

Extension:
glb
Full Name:
GL Transmission Format Binary (glTF 2.0)
Type:
3D Model
Format:
GLB
Tools:
Three.js、Babylon.js、Blender
Open With:
3D Model Viewer、GLB Viewer
Description:
GLB is the binary glTF 2.0 format from Khronos Group, packing meshes, materials, textures, and animations into one file. It is the standard for Web 3D and AR/VR, used by Three.js, Babylon.js, model-viewer, and e-commerce previews for self-contained, reliable distribution. GLB supports PBR materials, skeletal animations, Draco and Meshopt compression, suitable for web, AR, and cross-software use. However, it loses CAD parametric history when tessellated from STEP or native CAD. For 3D printing, use STL or 3MF as slicers cannot import GLB.

Notes:

  • Some 3D printing slicers cannot directly import GLB files
  • Not suitable for CAD parametric editing

Supported Features:

  • Single self-contained binary file
  • PBR material support (base color, metallic, roughness, normal maps)
  • Skeletal animation, skinning, and morph targets
  • Draco mesh compression and KTX2 texture compression
  • Multi-mesh nodes and scene hierarchy
