Turn glTF files into GLB without installing desktop software. Open the converter, drop your file, set the output options and download the result. Single files need no account.

Two-step conversion

source -> target

  1. Step 1 — Source

    glTF

    Drop or select a file: gltf plus buffers and textures. The converter reads the content on your device.

    Accepted input: gltf plus buffers and textures

  2. Step 2 — Target

    GLB

    Set the output options, run the conversion and download the GLB file.

    Units
    Model units (mm, cm, in)
    Orientation
    Y-up for web, Z-up for CAD and CAM
    Quality
    Triangle count or simplification target

The options above are the ones this converter exposes. Defaults are safe for most files; change them when your downstream tool expects specific units or orientation.

What this conversion does

Input

glTF

glTF is a JSON-based 3D runtime format with external buffers and textures.

Output

GLB

GLB is the binary form of glTF, a compact runtime format for web, AR and game engines.

Use this converter when you have a glTF file and the next step needs GLB, for example web viewers, AR and game engines. The conversion is handled by a dedicated tool, so you do not have to install a desktop application to move a single file.

Limitations

  • Conversions run in the browser and share the memory your device gives the page. Very large files are better handled on a desktop or with a cloud task.
  • Materials and textures survive only in formats that support them. STL carries geometry alone.

Frequently asked questions

Is glTF to GLB free?

Yes. This pair links to a converter that runs in your browser, and single-file conversions use a free daily allowance. No account is required to start, and you can register later for a larger allowance.

Do my files leave my device?

This pair links to a local browser converter, so the file is processed on your device and is not uploaded. Cloud processing, where a tool uses it, is labeled on the tool page and stores results only temporarily.

Can I convert several files at once?

Single-file conversion is available to everyone. Batch conversion is a paid capability, and cloud tasks have their own daily or monthly quotas. The pricing page lists the current limits.

What should I check after converting to GLB?

Open it in a web viewer or engine and check scale, orientation and materials.
