3D models

3DS → OBJ

Learn about the formats: What is OBJ?

Convert your legacy 3DS models into the widely compatible OBJ format for use across various 3D applications and game engines. This conversion is ideal for designers and developers needing to extract static 3D geometry and basic material data.

The 3DS format, historically associated with Autodesk 3ds Max, can contain complex scene data including geometry, materials, animation, and lighting. OBJ, on the other hand, is a simpler, open standard primarily focused on storing 3D geometry (vertices, normals, UVs) and referencing external material (MTL) and texture files. During the 3DS to OBJ conversion, our service extracts the static polygonal mesh data and fundamental material properties, converting them into the OBJ format and its accompanying MTL file, making the model accessible for broader use while shedding non-geometric scene elements.

Geometry is generally well-preserved, often maintaining the original triangulation. However, complex 3DS materials, specific shaders, animation, and lighting data will not be transferred to the OBJ format, leading to a simplification of visual properties.

Tips

Ensure all texture maps used in your 3DS file are present and correctly linked before conversion for proper material rendering in OBJ.
Simplify complex scenes in 3ds Max by removing unnecessary lights, cameras, and animation tracks if only the static model is needed.
Check for any vertex limit issues in older 3DS files (65536 vertices per mesh) as this might affect geometry integrity upon export.
Consider cleaning up redundant geometry or isolated vertices in the source 3DS model for a cleaner OBJ output.

Common use cases

Migrating older 3D assets from legacy 3ds Max projects into modern game engines like Unity or Unreal Engine.
Sharing static 3D models with collaborators who use different 3D software incompatible with 3DS.
Preparing models for 3D printing services that often prefer the simpler OBJ format for geometry validation.
Creating a lightweight version of a complex 3DS model for web-based 3D viewers or augmented reality applications.

Why ConvertX stays free — forever

We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.

🎁

Free tools today — and always

Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.

🔒

Privacy-first processing

Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.

3D models

Meshes and scenes for 3D printing, games, and CAD.

Common extensions: OBJ, STL, GLTF, GLB, FBX, PLY

Advantages

+ STL is standard for 3D printing
+ GLTF/GLB is optimized for the web and AR
+ OBJ is widely supported in 3D software

Disadvantages

− File size grows quickly with detail
− Materials and animations may not transfer
− Some formats lack units or scale metadata

🖼️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Advantages

+ WebP and AVIF offer excellent compression for the web
+ PNG keeps transparency and sharp edges
+ SVG scales without quality loss

Disadvantages

− RAW and TIFF files are large and slow to share
− JPEG loses quality on every re-save
− Some formats are not supported in older browsers

📄

Documents

Office files, PDFs, ebooks, and plain text.

Common extensions: PDF, DOCX, XLSX, PPTX, ODT, EPUB, TXT

Advantages

+ PDF locks layout for printing and sharing
+ DOCX and ODT are easy to edit collaboratively
+ Plain text works on any device

Disadvantages

− PDF is hard to edit without special tools
− Complex layouts may shift after conversion
− Scanned PDFs need OCR for editable text

🎬

Video

Clips, streams, screen recordings, and movies.

Common extensions: MP4, WebM, MOV, MKV, AVI, MPEG

Advantages

+ MP4 (H.264/H.265) plays almost everywhere
+ WebM is efficient for web embedding
+ MKV can hold multiple audio and subtitle tracks

Disadvantages

− High-resolution video needs lots of storage and bandwidth
− Re-encoding always takes time and may reduce quality
− Some codecs require licensing for commercial use

Frequently asked questions

No, the OBJ format does not support animation data. Only the static 3D model geometry and basic material references will be transferred.

The OBJ file will reference your texture maps via an accompanying MTL file. You will need to ensure the actual texture image files are located alongside the OBJ and MTL files for them to display correctly.

While OBJ can handle high polygon counts, the 3DS format itself has an older limitation of 65536 vertices per mesh. Our converter will process the geometry within these constraints, but very complex scenes might be broken down or simplified.

No, advanced render-specific materials will be simplified to basic diffuse colors and texture maps, or potentially lost, as OBJ and MTL only support fundamental material properties.
