MD2 to GLB Converter
Processing entirely on your device — large files may take a moment.
MD2 is the Quake II model format — a single vertex-animated mesh with keyframed frames baked in. Thousands of classic game models exist in it. GLB is what three.js, model-viewer, Unity and AR quick-look consume — the best choice for showing models on websites.
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.
How MD2 compares to GLB
| MD2 | GLB | |
|---|---|---|
| Structure | IDP2 header + frames + GL commands | Scene graph + mesh + animation |
| Compatibility | Quake II, three.js, ioquake3 | Web/AR/game engines native |
| Best for | Retro game model conversion | Web, AR and full 3D scenes |

About the MD2 format
MD2 is Quake II's model format: one mesh whose frames are baked vertex-by-vertex into the file — the original "vertex animation" that predates skeletal rigging. Every enemy, weapon and pickup in Quake II (1997) is an MD2, and the format became the de-facto standard for early modding.
three.js parses MD2 including its frame data, so a converted glTF carries the animation frames as morph targets — the retro look arrives intact in modern engines.
+ Strengths
- ✓Huge library of classic models
- ✓Frame data survives as morph targets
- ✓Simple binary layout
! Limitations
- −Fixed 8-bit texture skin
- −Small vertex budgets by modern standards
- −No materials beyond one skin
About the GLB format
GLB is the binary form of glTF 2.0 — the format the Khronos Group designed as “JPEG of 3D”. One self-contained file carries geometry, a full scene hierarchy, PBR materials with textures, skeletal animation and morph targets. It is the native asset format of three.js, Unity, Unreal, Blender and WebXR.
Converting to GLB is usually the upgrade path from OBJ/STL: materials become physically based and embedded, and scenes become portable in a single file. One honest caveat: Draco-compressed GLBs save space but many loaders need explicit decoder setup — plain GLB plays everywhere unconditionally.
+ Strengths
- ✓PBR materials, hierarchy and animation in one file
- ✓The web/AR standard — loads natively in three.js
- ✓Compact binary with texture embedding
! Limitations
- −Mesh-only: no CAD solids or NURBS
- −Older niche tools may not know glTF
Why convert MD2 to GLB?
Converting makes sense where the strengths of GLB meet what MD2 cannot give you. PBR materials, hierarchy and animation in one file Meanwhile Fixed 8-bit texture skin One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MD2 to GLB 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 MD2 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.
