Convert GLB files to 3MF in seconds. Geometry, UVs and materials are carried over where 3MF supports them, and the model lands the right way up.
Drop it on the converter above or click browse. It opens in your browser, so nothing is uploaded.
3MF is already selected. You can switch to any other output from the menu.
Click Convert and your 3MF file is ready in seconds. Download it straight away.
GLB is the single-file binary version of glTF, the open standard for 3D on the web. It packs geometry, materials and textures into one compact file that browsers, Android AR and most viewers load directly.
3MF is the modern 3D printing format from the 3MF Consortium. Unlike STL it records units, colours and multiple objects in one compressed file, and it is the native project format of Bambu Studio and PrusaSlicer.
Colours and texture coordinates are carried over when 3MF supports them. 3MF does not store textures, so only the geometry and colours carries over.
No. GLB and 3MF may use different "up" directions, and we rotate the model so it stands the same way in your software.
No. The conversion runs inside your browser.
