When you want OBJ instead of STL

OBJ is the lingua franca of modeling and rendering tools. Converting from STL gives you a mesh you can UV-unwrap, texture and render — the geometry is identical, just repackaged with merged vertices.

Frequently asked questions

Is this converter free?
Yes — up to 10 conversions a day and files up to 25 MB, no account needed. Larger files (up to 60 MB) and high-detail STEP output use credits ($9 for 20). Everything runs server-side on real geometry kernels, and failed jobs auto-refund.
What happens to my files?
Files are uploaded only to run your conversion and stored briefly so you can download the result. We don't share them, mine them or train on them. See our privacy policy.
