How to use GLB Model Compressor and Cleaner: practical workflow and checks
Use a real example to prepare input, run GLB Model Compressor and Cleaner, verify output, understand privacy, and respect current boundaries.
When to use it
Deduplicate, clean, and optionally simplify GLB with controlled precision, then compare and download. Phase one applies only transforms explicitly shown in the UI. Preserve the source and review precision, animation, and compatibility after lossy operations.
Practical example
If 35 MB of a 40 MB GLB is texture data, lossless deduplication may save little. Compare resource statistics and only expect major reduction when explicit texture transcoding is available.
Steps
- 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.
Checks after completion
- 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.
Do not rely on a success message alone. Sample counts, fields, dimensions, coordinates, text, or visual output against the source. Production, scientific, business, rights-sensitive, or formal deliverables require validation in the receiving system.
Current boundaries
- 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
Privacy and safety
Local files are processed in the browser tab and are not uploaded to FreeTool to perform the task. IIIF/DZI URLs are requested directly by the browser and remain subject to source logs, CORS, and access policy. Clear downloads, screenshots, and clipboard data after a shared device.
Common 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?
