How to use GLB Compressor
Phase one applies only transforms explicitly shown in the UI. Preserve the source and review precision, animation, and compatibility after lossy operations.
- Choose a GLB and record size, mesh, and texture statistics.
- Run deduplication and lossless cleanup first.
- Enable explicitly labeled geometry simplification only when needed.
- Compare animations, materials, and silhouette before download.
What this tool helps with
- Removes duplicated and unused resources
- Before/after statistics
- Processing runs in this browser tab; the file is not uploaded to FreeTool to perform the task.
Compatibility and limitations
- No default promise of Draco, Meshopt, or KTX2 transcoding
- Lossy simplification can damage detail, skinning, or morph targets
- Output requires regression testing in the target page or engine
Frequently asked questions
Why did size barely change?
The model may already be optimized or textures may dominate without transcoding.
Can compression break animation?
Lossless cleanup is lower risk, but inspect every animation after any lossy simplification.
Is the model uploaded?
