About This Tool
Convert multiple 3D models or ZIP archives to a single target format in one batch. Supports GLB, GLTF, OBJ, FBX, STL, 3MF, STEP, PLY, USDZ and more. Auxiliary materials and textures are auto-matched from file references. All conversion runs locally in your browser — files are never uploaded to any server.
Tips
- 1Convert up to 20 models in one batch
- 2Choose one output format for the entire batch
- 3Supports ZIP archives and auto-detected auxiliary files
- 4Per-file progress, errors, and download as ZIP
How to Use
Upload Models or ZIP
Drag and drop multiple 3D models or ZIP archives. Auxiliary files such as MTL, textures, and .bin buffers are matched automatically.
Choose Output Format
Select the target format for the entire batch and adjust conversion settings such as scale, coordinate system, and format-specific options.
Convert All & Download
Run batch conversion, review per-file status, then download individual files or a single ZIP archive.
Frequently Asked Questions
How many models can I convert at once?
Up to 20 models per batch. If you add more, only the first 20 are processed and the rest are skipped with a notice.
Can I upload ZIP archives?
Yes. ZIP files are extracted automatically and each model inside is added as a separate job. You can also mix individual model files and ZIP archives in one batch.
Can each file be converted to a different format?
No. One output format is selected for the entire batch. This keeps bulk conversion fast and consistent — choose GLB, OBJ, STL, FBX, or any other supported format before converting.
How are MTL, textures, and other auxiliary files handled?
Upload them together with your models or include them inside a ZIP. The tool reads file references inside each model and matches auxiliary files automatically. Unmatched files are reported as a warning.
What if some files fail during batch conversion?
Each model is processed independently. Failures are marked in the file list while successful models remain available for download individually or as part of the ZIP package.
What formats can I convert between?
You can convert to GLB, GLTF, OBJ, FBX, STL, 3MF, STEP, STP, PLY, and USDZ. Upload any supported input format including 3DS, and all models in the batch will be converted to your chosen output format.
Will textures and materials be preserved?
Texture and material preservation depends on the target format. GLB and GLTF fully support textures and materials. STL only preserves geometry.
Is my data secure?
Yes. All processing happens locally in your browser. Files are never uploaded to any server and data is cleared when you close the page.
