About this 3D converter
Convert compatible OBJ mesh geometry to STL when you need a simple triangle-based file for a downstream 3D-printing workflow. STL does not retain OBJ materials, textures, UVs, or scene hierarchy.
OBJ to STL for 3D printing
STL is widely supported by slicers, but it represents geometry only. Convert OBJ to STL when material appearance is not needed and you need a mesh for printing or basic interchange.
What OBJ data is not kept in STL?
STL does not preserve material assignments, MTL references, textures, UVs, object names, or a rich scene hierarchy. Check the STL in your slicer for scale, orientation, manifoldness, and printer-specific requirements.
OBJ files from Blender, Maya, and 3ds Max
Preview compatible OBJ geometry in a current Windows, macOS, or Linux browser after export from Blender, Maya, 3ds Max, SketchUp, or similar software. For the original appearance, select the companion MTL and texture images when the tool asks for them.
How to use this OBJ converter
- Sign in and unlock OBJ tools once.
- Upload a compatible .obj mesh file.
- Preview the geometry, then convert and download the STL for checking in a slicer or repair workflow.

OBJ converter FAQ
Can I convert OBJ to STL online?
Yes. This tool converts compatible OBJ mesh geometry locally in your browser after the OBJ format unlock.
Will OBJ textures appear in the STL?
No. STL is geometry-focused and does not preserve OBJ textures, MTL materials, or UV coordinates.
Is the exported STL ready to print?
Not automatically. Inspect it in a slicer or mesh-repair tool for scale, wall thickness, manifoldness, and printer-specific settings.
Do I need to install a OBJ to STL converter?
No. This compatible OBJ to STL conversion runs in a current browser after sign-in and the one-time format unlock.
Will every OBJ feature appear in the exported STL?
Not necessarily. Review geometry, scale, orientation, materials, textures, and animations after export because source-specific data may not have a STL equivalent.
Can I view an OBJ exported from Blender, Maya, or 3ds Max?
Yes, for compatible OBJ geometry. OBJ materials commonly depend on a separate MTL file and image textures, so include those companion files when you need to inspect the original look.
Is OBJ to GLB conversion processed online?
Compatible conversion is processed locally in your browser. Your source model is not uploaded to a conversion server by this workflow.
What should I check after converting OBJ?
Open the exported GLB and review geometry, scale, orientation, materials, and any animation before using it in a production scene or web page.
Is this OBJ converter a subscription?
No. The format unlock is a one-time $1.90 purchase; VIP members can also access the tool.
