BVH to PNG 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 PNG when you need lossless quality or a transparent background — for logos, UI screenshots and line art.
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 PNG format
PNG was created in 1996 as a free, open replacement for the patent-encumbered GIF, and it has been the reference lossless image format ever since. Pixels are compressed with the DEFLATE algorithm (the same one inside ZIP files), which reproduces the original image exactly — bit-for-bit — while supporting full 8-bit or 16-bit alpha transparency. Screenshots, logos, icons, charts and anything with text or sharp edges should live in PNG.
Because it never discards information, PNG files of photographs are several times larger than JPG — that is the price of perfection. Modern PNG encoders add filters per scanline that make screenshots and flat-color graphics compress surprisingly well. PNG also became the base of APNG, the animation extension that browsers play natively.
+ Strengths
- ✓Truly lossless — every pixel survives exactly as it was
- ✓Full alpha transparency with smooth edges, not 1-bit masks
- ✓Open standard, unpatented, with excellent tooling everywhere
- ✓Ideal for text, line art and flat-color graphics — sharp edges stay sharp
! Limitations
- −Photographs become several times larger than JPG
- −Base format has no animation (that is the APNG extension)
- −16-bit or high-resolution PNGs can grow very heavy
Why convert BVH to PNG?
Converting makes sense where the strengths of PNG meet what BVH cannot give you. Truly lossless — every pixel survives exactly as it was 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 PNG 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.
Will my PNG model keep its colors and textures?
Only if PNG 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.
