BVH to GZ Converter
Processing entirely on your device — large files may take a moment.
Biovision Hierarchy and Gzip Compressed File exist for different jobs: 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. Unpack a .gz into a normal file or repack it as ZIP/TAR when the receiving tool does not understand gzip.
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 GZ format
A .gz file is one file squeezed by gzip — not an archive. kernel.org tarballs are “tar inside gz”, but plenty of logs, JSON dumps and CSV exports travel as plain .gz. Opening one means decompressing it back to the original bytes.
Repacking into ZIP or TAR gives the decompressed file a container that every GUI tool opens without a second thought.
+Strengths
- ✓Everywhere on Linux and macOS
- ✓Fast, well-understood compression
- ✓Streams natively from any tool
!Limitations
- −Single file only — no directory tree
- −No encryption or integrity metadata
Why convert BVH to GZ?
Think of it as moving your file to the container that fits the job. No mesh — needs retargeting to a body GZ works differently: Everywhere on Linux and macOS 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 GZ 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 GZ?
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.
Are the files inside my BVH archive modified?
No. Contents are unpacked in memory and repacked into GZ byte-for-byte — the conversion changes the container, never the files inside it.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
