What You Get with Meshy's 3D Model Converter

All Major 3D Formats

Convert between OBJ, FBX, STL, GLB, GLTF, USDZ, 3MF, PLY and more — the format set that covers games, printing, AR/VR and product visualization pipelines.

Geometry & Texture Fidelity

Meshes keep their geometry, normals, UVs and material colors through conversion. GLB and GLTF round-trips preserve textures so your asset looks the same in every engine.

No Install, No Signup

Everything runs in the browser. Upload a model, pick a target format, download the result — no software, no account, no upload queue.

Everything You Need to Convert 3D Files

Popular file formats support

Work seamlessly with industry-standard formats including OBJ, USDZ, STL, GLTF, and more. Eliminate compatibility barriers between different 3D applications with comprehensive format conversion options.

No login & download required

Convert files instantly in your browser without software installation or account creation. Upload your 3D asset, select your output format, and transform your model with zero unnecessary steps.

Free to all 3D creators

Access professional-grade conversion technology at zero cost. We’ve removed financial barriers to empower students, indie developers, hobbyists, and professional studios with enterprise-level 3D conversion tools.

Insanely fast

Privacy protection

Your intellectual property remains secure. Files are processed at client side and will never leave your browser or uploaded to our server, ensuring complete confidentiality.

About the GLB File Format

The .glb file format is the binary container of glTF 2.0, the royalty-free 3D transmission standard maintained by the Khronos Group. A single .glb bundles the scene description, the binary geometry buffer, and every texture into one self-contained file, and it carries PBR metallic-roughness materials, full node hierarchy, skinning, and animation. Designed for efficient delivery rather than authoring, it has become the default format for the web, AR, and real-time engines.

Developer: Khronos Group
Based On: glTF 2.0 binary container (JSON + binary buffer + textures)
Common Software: Blender, Unity, Unreal Engine, three.js, Babylon.js

What Survives Conversion to GLB

Every 3D format carries a different slice of a scene. This is exactly what Meshy's converter writes into a GLB file, and what it leaves behind.

Model data	Result
Mesh geometry	Preserved
UV coordinates	Preserved
Materials and textures	Preserved
Animation and rigging	Preserved
Vertex colors	Preserved

GLB is the highest-fidelity target this converter offers. It is the only format here that carries animation clips through, and the only one that embeds PBR materials and textures in a single file, so whatever exists in your source model is most likely to survive as GLB.

Who Converts 3D Models with Meshy?

3D Printing Hobbyists

Turn game rips, downloaded models, or CAD exports into STL for your slicer — swap FBX to STL without learning a DCC tool.

Game Developers

Convert assets between engine-friendly formats: OBJ to GLB for web builds, FBX to GLTF for runtime loading, without breaking materials.

E-commerce & Product Teams

Prepare product models for 3D viewers on storefronts — GLB and USDZ cover every major platform's viewer format.

Architects & Visualizers

Bring CAD and SketchUp models into real-time renderers and AR previews by converting to the formats your toolchain accepts.

Frequently Asked Questions

They are the same format in two containers. A .gltf file is text that references external buffers and textures, while a .glb packs that description, the binary buffer, and every texture into one file. GLB is the better choice for sharing, which is why it is the default here.

Yes. The converter collects the animation clips from the source file, an animated FBX for example, and writes them into the GLB, so rigged and keyframed models keep moving. GLB is the only target format here that carries animation.

Yes. GLB is the glTF 2.0 binary container maintained by the Khronos Group, and all three import it natively with PBR materials and embedded textures intact, with no plugin required.
