BVH to WIM Converter
Processing entirely on your device — large files may take a moment.
Extracting WIM to ZIP exposes the files inside Windows images without deployment tools. If your files are still in BVH format, this page is the shortcut: BVH is the motion-capture skeleton format: a text hierarchy of joints with rotation channels and per-frame keyframes. It carries no mesh — only the skeleton and its animation.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the BVH format
BVH (Biovision Hierarchy) is motion capture in plain text: a joint hierarchy with rotation channels, followed by a MOTION block of per-frame values. It carries no mesh — which is exactly why it converts cleanly into glTF skeletons and animations.
The converted glTF carries the bone hierarchy and the animation clip, so a mocap take drops straight into three.js, Unity or Blender and can be retargeted onto any character.
+Strengths
- ✓Human-readable mocap standard
- ✓Clean glTF skeleton mapping
- ✓Decades of free mocap libraries
!Limitations
- −No mesh — needs retargeting to a body
- −Euler rotation gimbal quirks
- −Scale conventions vary per studio
About the WIM format
WIM (Windows Imaging Format) is how Microsoft ships Windows itself: the install media and deployment images are WIM files, holding a complete filesystem snapshot with single-instancing (identical files stored once). It is Windows' answer to tar — file-based rather than sector-based.
Opening one without deployment tooling (DISM, 7-Zip on Windows) is awkward. Extracting WIM to ZIP exposes the files inside — drivers, scripts, provisioned apps — on any system, no Windows required.
+Strengths
- ✓Windows' native image format
- ✓Single-instancing deduplicates identical files
!Limitations
- −Opaque without Microsoft tooling
- −Files inside may be Windows-locked
Why convert BVH to WIM?
Think of it as moving your file to the container that fits the job. No mesh — needs retargeting to a body WIM works differently: Windows' native image format If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this BVH to WIM converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will my model look the same as a GLB?
Geometry, hierarchy and standard materials convert faithfully. Note that Draco-compressed GLB files and exotic extensions are not supported — export those as plain GLB from your original tool first.
Will my WIM model keep its colors and textures?
Only if WIM can store them. Geometry converts faithfully; appearance data survives only when the target format has a place to put it. For full materials, GLB is usually the right target.
Does the scale or orientation of the model change?
Vertex data is converted as-is. Formats without a unit system (like STL) are interpreted as millimeters by most 3D-printing tools — scale before converting if your model uses different units.
