Free STL to OBJ Converter
Convert binary or ASCII STL to an OBJ ZIP free in your browser. Check scale and orientation, then download a static mesh without an account.
How to convert
- Choose your STL file.
- Check the preview, coordinate scale and orientation. Keep source numbers unless you intend to change units.
- Download OBJ ZIP. For OBJ, extract the ZIP and keep OBJ, MTL and any PNG files together.
What the export keeps
STL supplies geometry, not texture maps, UVs or a rig. The OBJ ZIP includes a neutral MTL material. Conversion does not recreate missing colors, textures or editable CAD surfaces. Coordinates and orientation are preserved by default.
Exports the current pose as a static mesh. The rig and animation are not included.
Advanced PBR effects, mirrored texture wrapping and vertex colors are not retained. Appearance may differ from the STL preview.
Common questions
Will conversion change the size or orientation?
By default, these conversions keep the source numeric coordinates and orientation. Use the explicit unit and axis controls when needed. OBJ and STL have no reliable unit tag; confirm dimensions after importing.
Is conversion free?
Local files stay in your browser. Export them freely without an account. AI-generated models, server rigging and AI motions retain their existing allowance and plan requirements.
