Are my GLB files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.

Is converting GLB to OBJ free?

Yes, without a limit on how many files you convert and with no watermark on the result. Files up to 100 MB are covered by the free plan.

Does converting GLB to OBJ lose quality?

GLB and OBJ describe content in fundamentally different ways, so the conversion is a reconstruction rather than a copy. The result is faithful, but not byte-for-byte equivalent. Geometry only. Materials, colours, textures and animation are not carried across, and a model placed several times comes back with each copy baked into its own position.

Do I need to install anything to open OBJ files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the OBJ afterwards needs whatever software normally handles Wavefront Object on your device.
