FBX to GLB

Turn an FBX into a GLB with its materials, pictures and animations, read back before you get it. Free, with no account or uploads.

Choose the .fbx and its pictures together. The GLB keeps its parts, materials, pictures and animations, in metres standing on Y.

Drop an FBX to turn it into a GLB

Or choose one. For an OBJ with its MTL and pictures, or a glTF with its .bin, choose them all at once.

How it works and help

A little help along the way

Follow these steps. Every option is explained underneath. Everything happens in your browser; the model is never sent anywhere.

  1. Open the modelDrop it on the page or press Choose a file. An OBJ shows its colours when its .mtl file and pictures are chosen with it; a .gltf needs its .bin and pictures too. Choose them all at once.
  2. Turn it roundDrag to turn it, scroll or pinch to zoom, and drag with the right mouse button or two fingers to move it. Fit brings the whole model back into view; Front, Top, Side and Corner look at it from those sides.
  3. Say its size, if it has noneSTL, OBJ and PLY files do not say what their numbers mean. The page reads STL files in millimetres, as 3D printers and CAD programs write them; if the size looks wrong, choose the unit the file was made in.
  4. Choose how fine curves are, for CAD filesSTEP, IGES and BREP files keep exact curves, which are cut into flat triangles to be drawn. Fine suits most parts; Very fine follows curves more closely and makes a larger model, Draft a quicker, coarser one.
  5. Measure itThe size of its box is shown at once, with its surface area, and its volume when it is a closed shape. Press Measure, then two points on the model, for the distance between them; a press near a corner snaps to it.
  6. Look insideCut slices through it across its height, width or depth. Parts lists every piece by name: hide one, or press it to see which it is.
  7. Save a picturePicture saves a PNG of the model as it is shown, at the size set under More options, on a clear background if you like.

Questions people ask

Are the animations kept?
Yes. The GLB keeps its skeletons and animations, with its parts, materials and pictures.
Will the GLB be the right size?
Yes. The FBX says its unit and which way is up, and the GLB is written in metres standing on Y, as glTF always is.
Is my FBX uploaded?
No. It is read and the GLB written in your browser on your device; nothing about it is sent anywhere.
