Unlimited conversions, one file at a time. Up to 50 MB and 1 million imported triangles per file. Your model stays on your device and is processed locally.

3D File Converter: Reference Models for Planning an Export

Explore sample GLB models to examine their shapes and surface detail. These visual references can help you plan which parts of a model matter for your next conversion.

3D File Converter for Scene, Mesh and Voxel Formats

Choose from six input and output formats to move existing 3D models between scene, polygon mesh and voxel workflows.

Six formats, 30 conversion directions

Select GLB, glTF, OBJ, STL, VOX or PLY as your source, then choose a different output. Convert an existing model for the application you want to use next.

Mesh and scene exports

Export GLB or embedded glTF for compatible real-time applications, OBJ or PLY for mesh tools, and binary STL for slicer preparation.

Mesh-to-voxel and voxel-to-mesh

Create a single-color VOX surface on a 64 × 64 × 64 grid from a mesh, or turn imported VOX surfaces into polygon geometry for another output format.

Download directly from your browser

Add one file up to 50 MB, convert it locally and save the result. Imported meshes can contain up to 1 million triangles.

Keep Your Workflow Moving with the 3D File Converter

Convert an existing model locally, keep the source and take the download into the viewer, editor or slicer you already use.

No account or generation credits

Convert supported models without an account or generation credits. Choose your file, run the conversion and download the output.

Keep model data on your device

Your file is processed inside your browser, so the converter does not need a server upload to produce the download.

No converter installation

Change the file format on this page, then open the download in the viewer, editor or slicer you already use.

Keep the source for future work

Each conversion creates a separate download. Retain the original asset for source edits and choose another output when a different workflow needs it.

3D File Converter Use Cases: Viewing, Editing and Print Preparation

Choose an output for the work ahead, from displaying a model online to preparing its surface for editing or printing.

Prepare assets for web viewers

Package compatible meshes as GLB or embedded glTF for a web viewer or real-time scene. Check their appearance in the application that will display them.

Move geometry between modeling tools

Export OBJ or PLY to continue surface cleanup and shape editing in compatible modeling tools. Review the available vertex data before starting texture work.

Prepare a mesh for 3D printing

Export STL for a slicer, then set physical dimensions and check closed surfaces and wall thickness. Conversion supplies the mesh; print preparation happens in your print tools.

Explore voxel art

Rework a mesh as a single-color VOX surface for block-based editing, or turn voxel artwork into polygon geometry for a wider range of 3D applications.
