What is an OBJ file?
OBJ is a widely used 3D format created by Wavefront. It stores the geometry of a model and is supported by Blender, Maya, 3ds Max, ZBrush and most slicers.
OBJ for 3D printing
Most slicers can print OBJ files directly. If you need an STL instead, convert it in one click with our STL converter.
Frequently asked questions
Is my file uploaded?
No. Everything runs in your browser. Your file is read locally and never leaves your device, so it is safe for private and paid models.
Is it free?
Yes, it is 100% free, with no sign-up, no watermark and no file limit.
Are textures and materials shown?
The viewer displays the geometry of the model with a single color, which is what matters for 3D printing. MTL files and textures are not loaded.
My model is lying on its side
OBJ files from 3D apps usually use Y as the up axis, while printing files use Z. Change the Up axis option in the View panel.
How do I convert OBJ to STL?
Open the file in our STL converter, choose STL and click download.
