BVH to XZ Converter
Processing entirely on your device — large files may take a moment.
Unpack XZ into ZIP/TAR for tools that cannot read LZMA2. 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.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

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 XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux
Why convert BVH to XZ?
Converting makes sense where the strengths of XZ meet what BVH cannot give you. Highest common ratio Meanwhile No mesh — needs retargeting to a body One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this BVH to XZ 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.
Is there a file size limit for BVH to XZ?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the BVH file.
Are the files inside my BVH archive modified?
No. Contents are unpacked in memory and repacked into XZ byte-for-byte — the conversion changes the container, never the files inside it.
