A .unitypackage is not a single 3D model. It is an archive that can contain FBX models,
textures, Unity materials, prefabs, scenes, animations, audio and project metadata. This browser tool opens
that archive locally and turns the supported 3D content into something you can inspect and use immediately.
How to extract a Unity package in the browser
- Choose the package. Drop the
.unitypackageonto the page or use the file picker. - Inspect what is inside. Browse the original Unity folders, scenes and supported 3D models.
- Preview before downloading. Open a model, prefab or scene and check its materials, LOD and saved character pose.
- Choose the useful output. Download a textured GLB, a compact ZIP of selected models, textures as PNG, animation FBX files, or the raw package contents.
Why models, materials and textures need to be resolved together
Unity usually connects assets through internal identifiers rather than simple file names. Extracting an FBX and a folder of images is therefore not always enough: another application may not know which image belongs in the base-color, normal, metallic or emissive slot. The converter follows those Unity references and builds standard PBR materials for the GLB wherever the package contains enough information.
What each download option is for
- Current preview as GLB: one model, assembled prefab or scene, with supported textures embedded.
- Selected models as a compact ZIP: many GLB files in their Unity folder structure, with shared textures stored once.
- Textures as PNG: a convenient image-only archive; images already in PNG or JPG remain unchanged.
- Animation FBX files: original clips for use in a DCC or engine when automatic rig binding would be unsafe.
- Raw package files: the closest available reconstruction of the files stored in the archive.
Private by design
The package is read by JavaScript running on your device. It is not sent to an extraction server. Large files can still take time because your browser must decompress, parse and convert them locally, but the source asset stays on your machine throughout the process.
Current limitations
The preview is a reconstruction, not the Unity Editor. Custom shaders, post-processing, scripts, particle systems and baked lighting do not have direct GLB equivalents. FBX is the supported 3D source format today. Very large packages are also limited by available browser memory. The interface reports these cases instead of pretending the conversion is identical to the original Unity project.
