Decimify SketchUp Pro removes the 30% reduction cap — the free slider is clamped at 30% of possible reduction; Pro removes that ceiling.
| Free | Pro | |
|---|---|---|
| Polygon reduction | Up to 30% | Unlimited |
| Lock Borders / Keep Creases / Keep UV | ✓ | ✓ |
| Smooth Angle control | ✓ | ✓ |
| Import GLB / STL | ✓ | ✓ |
| Preserves Groups, Components, Materials | ✓ | ✓ |
The 30% cap is the only difference between tiers — every option is available in both. If 30% reduction covers your use case, the free tier is complete.
