Does the model leave my machine?

No. The conversion runs as a local browser job and the model is not sent anywhere.

Which format should I choose?

Use GLB for web, AR and game-engine handoff, OBJ for editing in a modelling tool, and STL for 3D printing and slicers.

Mesh geometry does. Textures, materials and rigs may not be carried over, and STL has no colour data at all, so check the result in your 3D tool.

Up to 50 MB per file. Larger models need a desktop conversion tool.

One file per run. Load the next model once the current conversion is downloaded.

Convert common GLB, OBJ, and STL model files locally in the browser for 3D handoff workflows.

Browser-only, private

Convert common 3D model formats locally without uploading the file.

Pick a source and a target format, convert locally and download the result.

Pick the source format and file
Choose GLB, OBJ or STL as the source and select a file up to 50 MB. It is read locally in the browser tab instead of being uploaded.
Choose the target format
Supported conversions are GLB to OBJ, GLB to STL, OBJ to GLB and STL to OBJ. Unsupported pairs show an error before anything is processed.
Convert the model
Press Convert model. The converter writes a single mesh file in the target format.
Download and check
Save the file before closing the tab, then open it in the viewer or your 3D tool to confirm shape, scale and materials.

Do materials, textures and animations survive conversion?
Mesh geometry does. Textures, materials and rigs may not be carried over, and STL has no colour data at all, so check the result in your 3D tool.

How large can the source file be?
Up to 50 MB per file. Larger models need a desktop conversion tool.

Can I convert several models at once?
One file per run. Load the next model once the current conversion is downloaded.

Quick tips

Conversions run locally in the browser, so no model upload is required.
STL output keeps geometry only and drops materials or textures by design.
For production-critical assets, open the converted file in your target DCC or slicer before delivery.

Convert GLB to OBJ locally for Blender, Maya, mesh editing, CAD review, or handoff.

Convert GLB to STL locally for geometry-only 3D printing checks, slicers, and manufacturing review.

Convert OBJ to GLB locally for compact browser-ready preview, game handoff, or TripoSplat review.

Convert STL to OBJ locally when geometry needs a more editable mesh exchange format.
