About the GLB to glTF Converter
Need to turn a GLB file into glTF? This free converter changes GLB 3D models into glTF in a few seconds, right in your browser. People usually convert because many slicers and older 3D tools cannot import GLB, while glTF gives you a glTF scene with embedded buffers. glTF files open in Blender, Three.js, Babylon.js, Godot, Unity (with plugins) and VS Code.
Models are loaded and exported with three.js, the most widely used open-source 3D library for the web. Because everything happens on your own device, your 3D models are never uploaded, stored or seen by anyone else, which makes it safe for client prototypes and unreleased product designs.
What to expect: geometry, normals and UV coordinates are converted, and the model is not rescaled.
How to use the GLB to glTF Converter
- Click "Choose files" or drag your GLB 3D models onto the box. You can add several at once.
- No settings are needed.
- Press "Convert to glTF". The conversion runs on your device and shows its progress.
- Download each glTF file, or use "Download all (ZIP)" when you converted several.
- Open the result in Blender or Three.js to check it; your original GLB is never changed.
Tips & benchmarks
- The .gltf is written as a single file with its buffers embedded, so nothing goes missing.
- STL and OBJ files have no units; most slicers assume millimetres, so check the size after importing.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the glTF to a website or government portal.
Frequently asked questions
How do I convert GLB to glTF?
Click "Choose files", select your GLB 3D models, adjust the options if you want, and press "Convert to glTF". The glTF downloads immediately; with several files you can download everything as one ZIP.
Is this GLB to glTF converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your 3D models never leave your phone or computer and nothing is stored on News Appite's servers.
Are textures and materials kept?
Basic materials and vertex colours are carried over where both formats support them. External texture image files referenced by OBJ or glTF are not bundled unless they are embedded in the source.
Can I convert several GLB files at once?
Yes. Add as many GLB files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed.
What is the difference between GLB and glTF?
GLB (Binary glTF) is a single-file 3D scene best suited to web 3D viewers, AR on Android and Facebook, Three.js and Babylon.js. glTF (GL Transmission Format) is a JSON 3D scene best suited to inspecting or editing 3D scenes by hand and web 3D pipelines.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
How do I convert GLB to glTF in Python?
Use trimesh: trimesh.load('input.glb').export('output.gltf'). If you just need the file, this converter does it in the browser without writing any code.
GLB ko glTF kaise kare?

What is a GLB file?
GLB is the binary, single-file version of glTF 2.0, often called the "JPEG of 3D". Meshes, materials and textures are packed into one compact file that loads fast on the web, in AR and in game engines.
What is a glTF file?
glTF is the Khronos Group's open standard for transmitting 3D scenes efficiently. The .gltf variant is human-readable JSON that describes meshes, materials, animations and cameras.
