What is FBX?
FBX (Filmbox) is a proprietary format developed by Autodesk. It supports geometry, materials, textures, animations, bones, and blend shapes — making it the go-to exchange format for game engines and animation pipelines.
Why optimize FBX?
FBX files are typically large and not optimized for web delivery. They contain uncompressed geometry, high-resolution textures, and redundant data from DCC tools. Optimization converts FBX to compressed GLB, reducing file size by 60-95% while preserving all visual detail and animations.
What gets optimized?
Trice converts FBX to GLB, then applies meshopt compression, texture conversion to WebP, texture resizing, vertex welding, and geometry deduplication. Animations, bones, and blend shapes are preserved.
How it works
Drop your .fbx file
Drag and drop or click to select your FBX model.
Auto-optimize
Trice compresses meshes, optimizes textures, and deduplicates geometry — all in your browser.

Frequently asked questions
Yes. Skeletal animations, blend shapes (morph targets), and keyframe animations are fully preserved during conversion and optimization.
Put the FBX file and all its texture files into a ZIP archive, then drop the ZIP here. Trice will automatically match textures to materials and optimize everything together.
Substantial reduction. FBX to optimized GLB typically achieves 70-95% file size reduction. A 100 MB FBX with large textures can easily become 5-10 MB.
Both ASCII and binary FBX formats are supported, including FBX 2014 and newer. Files from Maya, 3ds Max, Blender, Cinema 4D, and other DCC tools are all compatible.
