3D models

FBX → glTF

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

Convert your professional 3D models from the industry-standard FBX format to GLTF, the efficient format for web and real-time applications. This conversion is essential for deploying interactive 3D content online or integrating assets into modern engines.

FBX, a proprietary format by Autodesk, is a robust container for high-fidelity 3D data, including complex animations, materials, and rigging, widely used in professional DCC tools. GLTF, an open standard by Khronos Group, is optimized for efficient transmission and loading of 3D scenes on the web and in real-time engines, focusing on runtime asset delivery. During conversion from FBX to GLTF, our service processes your model's geometry, textures, animations, and PBR materials, translating them into the GLTF structure while optimizing for web-friendliness and performance.

Core geometry, UVs, skeletal animations, and PBR material properties generally transfer with high fidelity. However, highly complex or proprietary shading networks from FBX might require simplification or remapping to GLTF's PBR workflow, potentially leading to minor visual adjustments.

Tips

Ensure textures are correctly linked and embedded within your FBX file for seamless transfer.
Simplify complex material setups in FBX to standard PBR metallic-roughness before conversion for best results.
Check for unnecessary nodes or empty groups in your FBX model to optimize the final GLTF file size.
If animations are crucial, verify their playback in a GLTF viewer after conversion.

Common use cases

Publishing 3D product configurators or interactive models on e-commerce websites.
Integrating game assets from professional modeling software into web-based game engines or AR/VR experiences.
Sharing 3D architectural visualizations efficiently with clients via a web browser.
Developing lightweight 3D scenes for mobile applications where performance is critical.

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

Yes, skeletal animations, skinning, and blend shapes (morph targets) are generally supported and will transfer to the GLTF format.

Our converter will attempt to map your FBX materials to the GLTF PBR (Physically Based Rendering) metallic-roughness workflow. Complex proprietary shaders might be simplified.

Often, yes. GLTF is designed for efficient delivery, and the conversion process can include optimizations that result in a smaller, more performant file suitable for web use.

Yes, GLTF supports hierarchical scenes. The converter will translate the scene structure and individual objects from your FBX file into the GLTF format.
