It is shown that some new extensions of Hilbert's integral inequality with parameter can be established by introducing a proper weight function. In particular, when , a refinement of Hilbert's integral inequality is obtained. As applications, some new extensions of Widder's inequality and Hardy-Littlewood's inequality are given.
