What to know about GLTF to OBJ conversion

- Use glTF files with embedded buffers, or convert the GLB version: external .bin and texture files are not read.

Frequently asked questions
Is it safe to convert GLTF to OBJ here?
Yes. Your files are processed entirely on your own device by WebAssembly code running in the browser. They are never uploaded, so nobody else can see them, and the converter keeps working even if your connection drops after the page loads.
Is there a file size limit?
There is no server-side limit. The only limit is the memory available to your browser, typically 1.5–4 GB on desktop computers.
Can I convert several GLTF files at once?
Yes. Add as many files as you like; they are converted in parallel according to your device's CPU cores, and you can apply the same settings to all of them.
