We obtain L-2 x L-2 -> L-1 boundedness for bilinear maximal functions associated with general compact hypersurfaces. Our method is based on the strategy introduced by Barrionuevo et al. [Math.
Res. Lett. 25 (2018), pp. 69-1388] and a new multiplier result established by Grafakos, He, and Slavi ' kova[Math.
Ann. 376 (2020), pp. 431-455].
