How to reduce polygon count online
The reducer helps reduce polygon count online by dividing the model's bounding volume into a target-driven grid, mapping nearby interior vertices into shared representatives, and removing duplicate or flattened faces. Boundary and sharp-feature options keep selected vertices from being collapsed as aggressively. The final count can differ from the target because topology and preservation rules limit safe merges.
| Goal | Useful setting | Reason |
|---|---|---|
| Reduce polygon count preview | Lower target, Triangle | Fewer faces are quick to draw |
| Game blockout | Moderate target, Quad Dominant | A lighter surface is easier to iterate |
| Hard-surface silhouette | Preserve Sharp Edges | Keeps high-angle feature vertices |
| Open scan | Preserve Boundaries | Protects cut and border edges |
Reduce polygon count without losing the source
Always keep your original model. To reduce polygon count safely, treat the operation as lossy: a lower count can remove small bevels, scan noise, or thin structures. Compare the solid and wireframe previews, then use the downloaded OBJ only when the trade-off fits the intended task. Reduce polygon count gradually when the silhouette matters.
Common uses for reduce polygon count
Real-time previews
Use reduce polygon count to create a lighter mesh for quick viewport and browser testing.
Scan experiments
Reduce dense capture geometry before deciding how to clean it manually.
Game prototypes
Explore a lower-poly silhouette before final asset production.
Reduction is not repair
A polygon reducer does not automatically fill holes, fix non-manifold edges, unwrap UVs, or optimize materials. If the model must be printed or rigged, use the reduced OBJ as an intermediate and run the checks required by that workflow.
