In this work, we present the package {\sc NeatIBP}, which automaticallygenerates small-size integration-by-parts (IBP) identities for Feynmanintegrals. Based on the syzygy and module intersection techniques, thegenerated IBP identities' propagator degree is controlled and thus the size ofthe system of IBP identities is shorter than that generated by the standardLaporta algorithm. This package is powered by the computer algebra systems {\scMathematica} and {\sc Singular}, and the library {\sc SpaSM}. It isparallelized on the level of Feynman integral sectors. The generated small-sizeIBP identities can subsequently be used for either finite field reduction oranalytic reduction. We demonstrate the capabilities of this package on severalmulti-loop IBP examples.
