Why Convert OBJ to GLTF?

OBJ is the universal editing format. glTF is the universal delivery format. Convert your models for the modern web.

Web Deployment

glTF is the standard for three.js, Babylon.js, Google Model Viewer, Facebook 3D Posts, and Shopify. Deploy your OBJ models directly to the web platform.

PBR Material Conversion

OBJ MTL data is upgraded to glTF's PBR metallic-roughness workflow. Base colors, textures, and material properties convert to modern physically-based materials.

Draco Compression

Optional Draco mesh compression can reduce file size by 90%+. Dramatically faster downloads, CDN efficiency, and mobile bandwidth savings for complex models.

AR/VR Ready

glTF is the format for Apple AR Quick Look, Android Scene Viewer, Meta Spark, and WebXR. Convert OBJ to glTF to deploy models in augmented and virtual reality.

About OBJ to GLTF Conversion

Why convert OBJ to GLTF?

OBJ (Wavefront) is the universal static mesh format, simple, text-based, and supported by every 3D tool. glTF 2.0 is the Khronos Group's modern standard. The "JPEG of 3D" designed for efficient transmission and loading in web browsers, mobile devices, and AR/VR applications. Converting OBJ to glTF prepares your models for the modern 3D web: compact binary storage, native PBR materials, animation support, and direct integration with three.js, Babylon.js, and every major web 3D framework.

What is preserved during conversion?

Mesh geometry, all UV map sets, and vertex normals are fully preserved. MTL material data: diffuse colors, texture references, and specular properties is converted to glTF's PBR metallic-roughness workflow. Textures are referenced by relative path in the glTF output. Optional Draco compression dramatically reduces mesh data size. Note that OBJ does not contain animations, so the glTF output will be a static mesh, animations must be added in your target application or authored separately.

How to use the converted GLTF file

The glTF output (.gltf + .bin + textures) loads directly into three.js, Babylon.js, PlayCanvas, Google Model Viewer, Facebook 3D Posts, Apple AR Quick Look, Android Scene Viewer, Unity, Unreal Engine, Godot, and Blender. For single-file delivery, use our GLTF to GLB converter to package everything into one binary file. Ideal for CDN hosting and e-commerce platforms.

How to Convert OBJ to GLTF

Three steps to upgrade your OBJ meshes to modern glTF 2.0 for web and real-time use.

1

Upload Your OBJ File

Drag and drop your .obj file (and optional .mtl + textures). Our engine auto-detects MTL files. Enable Draco compression for smaller file sizes. Free tier: up to 50MB.

2

Convert to glTF

Our cloud engine reads OBJ/MTL data, converts materials to PBR, applies optional Draco compression, and writes clean glTF 2.0 output with all textures preserved.

3

Download & Deploy

Download your glTF and load into three.js, Babylon.js, or convert to GLB for CDN hosting. Files auto-delete from our servers within 1 hour.

FAQ

Frequently Asked Questions

OBJ is the universal static mesh format from the 1980s simple vertex/face/UV lists with MTL materials. glTF 2.0 is the modern Khronos standard compact binary/JSON storage, native PBR metallic-roughness materials, scene hierarchy, and animation support. OBJ is for editing; glTF is for web and real-time delivery.
Yes. You can convert up to 3 files per day for free with files up to 50MB each. For unlimited conversions, 500MB files, Draco compression, and batch processing, upgrade to Pro ($9.99/month).
Yes. MTL diffuse/albedo colors map to glTF's baseColorFactor, and texture references become baseColorTexture. Specular data and shininess inform the roughness value. The result is a basic PBR material that renders correctly in three.js, Babylon.js, and all glTF viewers. For advanced PBR, assign metallic/roughness/normal maps in your target application.
Draco is Google's open-source mesh compression library. It can reduce glTF geometry size by 90%+ by cleverly encoding vertex positions, UVs, normals, and indices. Use it for models you're deploying to the web or mobile dramatically faster downloads and lower bandwidth. Do not use Draco when you need to edit the mesh: compressed geometry must be decompressed at runtime.
glTF is supported by three.js, Babylon.js, Google Model Viewer, Facebook 3D Posts, Apple AR Quick Look (iOS), Android Scene Viewer, Microsoft Mixed Reality, Unity, Unreal Engine, Godot, Blender, Sketchfab, Shopify, and dozens more. It is the universal format for web and real-time 3D.
Absolutely. All uploads use TLS 1.3 encryption. Files are processed in isolated cloud environments and auto-deleted within 1 hour. Read our Privacy Policy for full details.
Free users: 50MB. Basic: 100MB. Pro: 500MB. Team: 1GB. With Draco compression enabled, the output glTF can be significantly smaller than the input OBJ.
