**SUePDF** is a graphic-user-interface program written in MATLAB to achieve quantitative pair distribution functions (PDF) from electron diffraction data. The program facilitates the structural studies of amorphous materials and small nanoparticles based on electron diffraction data from transmission electron microscopes (TEM). SUePDF is distributed as free-to-use software. [\[Publication list\]] **Please cite:** Dung Trung Tran, Gunnar Svensson and Cheuk-Wai Tai, 2017, *J. Appl. Cryst.*, **50**, 304-312.
