3D models

FBX → OBJ

Learn about the formats: What is OBJ? What is FBX?

Convert your rich FBX 3D models into the widely supported OBJ format for simpler geometry exchange. This conversion is ideal for users needing to share static 3D assets across various platforms and applications.

FBX is a feature-rich format supporting advanced data like animations, rigging, and complex scene hierarchies, primarily used in professional animation and game development. OBJ, on the other hand, is a more fundamental format, focusing primarily on storing polygonal geometry, UV coordinates, and referencing basic materials via an accompanying .MTL file. When converting FBX to OBJ, the core 3D mesh, its UV mapping, and texture references are extracted, while dynamic elements like animations, bone structures, and intricate material shaders are not transferred due to OBJ's limited scope.

Geometry and UV data are generally preserved with high fidelity during FBX to OBJ conversion. However, animated properties, rigging, and advanced material definitions present in the FBX file will not be retained in the resulting static OBJ model.

Tips

Flatten Animations: If your FBX contains animations, ensure you only need the static pose; animations will be lost.
Check Material Paths: Verify that texture files referenced in the .MTL file are correctly located relative to the OBJ for proper rendering.
Simplify Before Conversion: Remove unnecessary lights, cameras, or complex rigging from the FBX if they won't be used, as they won't transfer.
Export Single Meshes: For cleaner results, consider exporting individual meshes from complex FBX scenes rather than an entire scene graph.

Common use cases

Game Engine Asset Import: Importing static 3D models into engines that prefer simpler geometry formats like OBJ (e.g., for props or environmental assets without animation).
3D Printing Preparation: Converting animated or rigged models into a static, clean mesh suitable for 3D printing services.
Cross-Software Compatibility: Sharing basic 3D geometry with users of software that has better OBJ support or limited FBX import capabilities.
Archiving Static Models: Storing a clean, static version of a 3D model without its complex animation data for long-term archival.

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, OBJ format does not support animation data. Only the static mesh at its current pose will be converted.

Textures are usually referenced correctly, and basic material properties (like diffuse color) are translated into an accompanying .MTL file. Complex shaders are not transferred.

No, the polygonal geometry itself is typically preserved without loss of detail. The 'loss' refers to non-geometric data like animations or rigging.

Yes, the converter will typically combine or group the meshes into a single OBJ file, often preserving object names as groups within the OBJ.
