Reduce polygons

Simplify heavy meshes while keeping the shape: fewer triangles, lighter files and faster slicing. UVs and vertex colors are preserved.

What this tool does

How it works

  1. 01

    Upload the heavy mesh

    3D scans, ZBrush sculpts or photogrammetry with millions of triangles.

  2. 02

    Pick a percentage

    50%, 25% or a custom value. The split view shows original and simplified side by side.

  3. 03

    Download the light version

    Fewer triangles = faster slicing, manageable files and smooth viewports.

Frequently asked questions

How many triangles does a 3D print need?

For a typical part (5–15 cm), 100k–500k triangles capture every detail a 0.4 mm nozzle can reproduce. A 5M-triangle scan doesn't print any better — it just slows everything down.

Will I lose detail when simplifying?

The algorithm collapses the triangles that contribute least to the shape first (flat areas, redundant density). Up to ~75% reduction the change is usually invisible; the before/after view lets you judge.

Why doesn't trying several percentages degrade the model?

Every simplification starts from the original file, never from the previous result — you can try 50%, then 10%, then 25% without stacking loss.

Is it useful for game or web assets?

Yes: bringing an asset down to 10–50k triangles makes it real-time friendly. Export to GLB afterwards for an engine- and web-ready file.
