What changes in this conversion

  • The geometry (vertices and faces) is converted exactly. Material, texture and animation data is only carried over when both formats support it — OBJ keeps what it can and drops the rest.

How to use

  1. Add your GLTF file

    Drag the GLTF file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. Confirm OBJ as the output

    OBJ is already selected as the output format on this page. This format converts straight through with no extra settings.

  3. Run the conversion

    Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.

  4. Download the OBJ file

    When it finishes, download the OBJ file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions

Is converting GLTF to OBJ really free?

Yes. GLTF to OBJ conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my GLTF files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the GLTF file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Does the OBJ file get bigger than the GLTF?

It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.

Is there a file size limit for GLTF to OBJ conversion?

The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
