Questions

How much smaller will my file get?

File size falls roughly in line with the triangle count. Keeping 25% of the triangles usually gives a file around a quarter of the size.

Will it change the shape?

Only slightly. We report the largest change as a percentage of the model's size, so you can choose a level you are happy with.

Are my files uploaded?

No. Compression runs in your browser.
