Convert STL meshes to OBJ for DCC tools and pipelines that prefer OBJ + MTL.

Long conversions: leave and come back

You can leave, close, or refresh this page while converting — the job keeps running on the server.
If the server is busy, your job waits in a queue and shows its position.
After the conversion finishes, you have about 1 hour to download the file.
Come back in the same browser on this device so we can find your job.
To stop this task and choose another file, use “Cancel and upload again” in the progress box.

How it works

Is STL to OBJ conversion free?

Yes. AnyConv365 lets you convert STL to OBJ online for free with no account required.

Will my file quality be preserved?

We aim for the best practical fidelity for each pair. Preview the download before sharing when quality is critical.

Do you store my files?

Server-side source files are deleted immediately after a successful conversion. If conversion fails, the source file is retained for up to one hour for error diagnosis and then deleted automatically.

Does STL keep materials?

STL is geometry-focused and usually has no rich materials. Use GLB/GLTF when you need textures and PBR data.
