Cura, PrusaSlicer, Bambu Studio, Blender, Fusion 360, SolidWorks
Strength
Universal support in 3D printing software.
Limits
Only triangles: no colours, no materials, no units, no editable CAD features.

Questions

Are materials and textures kept?

Colours and texture coordinates are carried over when STL supports them. STL does not store textures, so only the geometry carries over.

Will my model be upside down?

No. OFF and STL may use different "up" directions, and we rotate the model so it stands the same way in your software.

Are my files uploaded?

No. The conversion runs inside your browser.
