BVH to JPEG Converter
Processing entirely on your device — large files may take a moment.
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. Convert to or from JPEG when a tool or form specifically asks for the .jpeg extension — the pixels and compression behave exactly like JPG.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

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 JPEG format
JPG (short for JPEG, the Joint Photographic Experts Group committee that standardized it in 1992) has been the default photo format for over three decades. It compresses photographs using the discrete cosine transform: the image is split into 8×8 blocks, and details the human eye is bad at noticing are discarded. The result is files many times smaller than uncompressed data, at a quality level you control when saving.
In practice JPG is unbeatable for photographs and smooth gradients — camera memory cards, messaging apps and the web all assume it. It is a poor fit for screenshots, logos or anything with sharp edges and flat color, where compression leaves visible ringing around text. There is no transparency support, color depth is capped at 8 bits per channel, and every re-save with compression compounds tiny generational losses.
+ Strengths
- ✓Opens on literally every device, app and browser made in the last 30 years
- ✓Compresses photos dramatically — typically 10:1 or better with little visible loss
- ✓Quality level is adjustable, so you can trade fidelity for file size
- ✓Mature ecosystem: EXIF metadata, ICC profiles and progressive loading all supported
! Limitations
- −Lossy — artifacts appear on text, sharp edges and flat areas
- −No transparency, so overlays and logos need PNG or WebP instead
- −Repeated re-saving at low quality permanently degrades the image
Why convert BVH to JPEG?
Converting makes sense where the strengths of JPEG meet what BVH cannot give you. Opens on literally every device, app and browser made in the last 30 years 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 JPEG 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.
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.
How large can the BVH file be?
Everything runs on your device, so memory is the only ceiling. Dense meshes with millions of triangles convert fine on a desktop computer, just over a slightly longer coffee break.
