FBX to GLB Converter

Turn FBX props and characters into a single GLB for the web or AR, with materials and textures embedded and the FBX unit scale converted to metres.

    How to convert FBX to GLB

    1. Drop your FBX files

      Drop .fbx files (FBX 7.0 or newer, binary or ASCII) with any separate textures.

    2. Check the preview

      The model appears at the size and orientation it will have. Fix the file units, up axis or size under Size, units and orientation if needed.

    3. Choose GLB options

      No options needed: GLB is written in metres, Y up, with materials and textures embedded.

    4. Convert and download

      One file downloads straight away. A batch gives a download per file and one .zip of all of them.

    What carries over from FBX to GLB

    Worked out from what each format can store and what this converter writes. Nothing is changed silently: the preview shows the size and orientation before you download.

    Geometry Every face is kept; quads and n-gons are split into triangles.
    Color Kept: materials, textures and vertex colors are embedded.
    Units Converted from the declared unit to metres, so it keeps its real size. A 50 mm part is written as 0.05.
    Orientation Both are Y up, so it stays the right way up.
    Objects Each part stays a separate object or mesh.
    Animation Dropped: the model is written in its rest pose.

    FBX to GLB: what actually happens

    GLB is the modern, open replacement for FBX on the web. The converter reads binary or ASCII FBX, applies its unit scale, and writes a GLB in metres with every mesh, material and texture embedded.

    Animation and skeletons are not carried; the meshes are written in their bind pose. For animated characters, use Blender's glTF exporter, which converts rigs and actions.

    FBX began as Kaydara's FiLMBOX and has been owned by Autodesk since 2006. It is the standard for moving rigged, animated characters between DCC tools and game engines; the format is proprietary, so most tools read it through Autodesk's SDK or reverse-engineered readers.

    glTF 2.0 is the Khronos Group's "JPEG of 3D", and GLB is its single-file binary form. It is what AI 3D generators, Sketchfab downloads and web apps hand out, and it is the only common format whose units (metres) and axes (Y up) are fixed by the spec.

    Tips for FBX to GLB

    Static props

    Furniture, products and environment pieces convert cleanly.

    Animated characters

    Use Blender (File, Import FBX, then Export glTF) to keep animations.

    Check size

    FBX files with a wrong unit scale show up at the wrong size; fix it with the file units option.

    FBX to GLB FAQ

    Does FBX to GLB keep animations?
    No. This converter writes static meshes. Blender's glTF exporter carries animations.

    Are textures embedded?
    Yes, embedded FBX textures and images you drop alongside are packed into the GLB.

    Is the size right?
    The FBX unit scale is applied and converted to metres, so the GLB keeps the size the FBX declared.

    Is the converter free? Are there limits?
    Free, with no sign-up, watermark or file count limit. Batches and files of a few hundred MB work on most laptops; the only limit is your device's memory.

    Are my files uploaded?
    No. Files are read and written by JavaScript and WebAssembly in your browser and never sent to PrintPal. The STEP and IGES reader is the only extra download, once, from a public CDN.
