Frequently asked questions
Does the model get colors or textures?
No, STL only contains the shape. Assign colors and materials afterwards in your 3D program.

Yes, drop the OBJ file in and pick STL as the target.
How does this tool work?
Converts files across multiple domains (3D/CAD meshes, video, raster & vector graphics, firmware & ROMs, structured datasets, documents, audio) directly in your browser.
Drop files into the upload zone or select them via file picker. The tool automatically detects each file category and populates compatible target formats. Convert files individually or in batch with a live progress bar, then download them one by one or bundled into a single ZIP archive. All processing runs 100% locally on your machine.
