FBX is the interchange heavyweight between DCC tools and game engines, but raw FBX payloads are notoriously bloated — dense meshes, baked animation curves and embedded media add up fast.

This FBX compressor re-encodes the geometry with Draco or meshopt compression and prunes redundant data, delivering an optimized GLB that web viewers and engines load natively. Animated rigs keep their clips — the model just stops weighing a hundred megabytes.

Compress FBX when you need to:

  • Put animated FBX assets on the web without huge downloads
  • Prepare character and prop models for three.js or Babylon.js
  • Get under strict upload limits on platforms and stores

How to Compress a 3D Model Online

1

Upload your FBX file

Drag the file onto the drop zone or click to browse. It is processed entirely in your browser — nothing is uploaded to a server.

2

Choose a compression preset

Pick Light for gentle cleanup, Balanced for the best size-to-quality trade-off, or Max for the smallest possible file.

3

Download the optimized model

Preview the result, check the size savings and download. If the file cannot shrink further, you get the original back.

3D Compression — Frequently Asked Questions

How do I compress an FBX file?+

Upload the FBX to the tool above, choose a preset and compress. Geometry is re-encoded with Draco or meshopt in your browser and the optimized model downloads as GLB — no server ever sees the file.

Does FBX compression keep animations?+

Yes — animation clips that the glTF pipeline can carry are preserved in the output. Skeletal and keyframed animations survive; only the mesh payload is re-encoded and slimmed down.

What output format do I get?+

An optimized GLB. It's the standard web replacement for FBX: one binary file with geometry, materials and animations that every modern 3D viewer and engine reads directly.

Will my FBX model look different after compression?+

No visible difference at Light and Balanced presets — vertex positions, normals, UVs and materials are preserved exactly. Max preset aggressively simplifies meshes for preview use and is clearly labeled as such.
