3MF to GLB converter

Drop a 3MF file, check the preview, download GLB. The conversion runs in your browser, so your model never leaves your device.

Files are processed entirely in your browser. Nothing is uploaded to a server.

Any 3D edit is just a prompt away.

How the conversion works

3MF is the modern print format used by Bambu Studio, PrusaSlicer, and Cura. Unlike STL it stores units, colors, and multiple objects per file.

The converter writes GLB, so the result loads directly in web viewers, e-commerce embeds, and most game engines.

Only the mesh geometry is taken from the 3MF. Slicer settings, plate layout, and metadata stay behind.

Frequently asked questions

Does my file get uploaded?

No. Parsing and export run in your browser with WebAssembly and three.js. The file stays on your device, and it works offline once the page has loaded.

What survives the 3MF to GLB conversion?

Geometry comes through completely: every triangle, at full precision. Materials, textures, and vertex colors don't, because the pipeline works on plain geometry. The GLB you download is ready to texture in Blender or a web viewer.

Is there a file size limit?

Models up to 8 million triangles work. STL files can be any size below that; other formats stop at 300 MB. Heavier meshes take longer rather than failing outright; if a file is unwieldy, reduce its triangle count first with the reduce tool.
