Poly Reducer 3D

Poly Reducer 3D lightens your 3D models directly from your phone.

Open an STL or OBJ file, move the slider, and reduce the number of triangles

while maintaining the model's shape. Perfect for 3D printing, sharing

lighter files, or preparing models for apps and games.

FEATURES

• Open .STL and .OBJ files (ASCII and binary)

• High-quality polygon reduction (edge-collapse) with real-time preview

• Quickly view original, current triangles, and estimated file size

• Export back to STL or OBJ

• Viewing modes: wireframe, faceted, smooth

• Rotate and orient the model: with your finger or with exact degrees (X/Y/Z)

• Fixed views (front, back, side, top, bottom) and turntable auto-rotation

• iOS-style interface, light and dark theme, customizable palettes

• Works offline too

No account, no hassle: open, reduce, export.
