Convert gltf binary files

The binary glTF format. The standard way to put a 3D model on the web. One chunked binary file holding a JSON scene description plus the geometry, textures and buffers it refers to, all in one. That is the format you end up with when something needs to look the same on every screen, which is why it keeps turning up in putting a product model on a website. From here it can become STL and OBJ, and the conversions run on your own device, so the file is never uploaded anywhere. The remaining 2 conversions are next in the queue and will be free.

    About the format

    The binary glTF format.

    One chunked binary file holding a JSON scene description plus the geometry, textures and buffers it refers to, all in one.

    Where it is good
    • A single file — geometry, textures and animation together
    • The format every web 3D library loads first
    • Compresses well and renders fast on the GPU
    Where it falls short
    • Only for real-time rendering, not for CAD or printing
    • Textures must be embedded or fetched separately
    • Meshes have to be simplified to stay performant
    You will find it on
    Web 3D, game engines, AR viewers, Sketchfab

    The thing people miss

    A GLB with embedded textures is one file, which is why a 3D product configurator can be a single download rather than fifty.

    How to

    Converting a GLB file

    1. 01

      Add your gltf binary

      Drag the file onto the drop zone, or tap to browse. Only one file is needed.

    2. 02

      Pick what you want it to become

      Every format this file can become is listed in the switchboard. Pick one and the converter opens with sensible defaults already set.

    3. 03

      Download the result

      Your converted file downloads straight to your device. Nothing was uploaded, so there is no file to delete from a server afterwards.

    Questions

    GLB conversion questions

    How do I convert GLB to another format?

    Add your gltf binary file to the drop zone, choose the target format, adjust the options if you want to, and press convert. The finished file downloads immediately.

    Is my file uploaded anywhere?

    For most conversions, no. They run entirely inside your browser tab. The file is read from your device and the result is written back to your device.

    Do I need an account?

    No. There is no signup step, no email capture and no usage counter. Open the tool, convert the file, close the tab.

    Will there be a watermark or a page limit?

    Neither. On-device conversions produce a clean file with no branding and no cap on pages, size or number of files.
