The interaction of a tilted magnetic field and the intrinsic anisotropy of magnetic thin films leads to profound effects on the deformation, orientation, and stability of the skyrmion crystal (SkX) phase, which has yet to be explored comprehensively. Here, we study the combined effects of a tilted magnetic field and the exchange anisotropy on SkX in thin films of helimagnets. By applying an analytical framework suitable for deformed or rotated SkX, not only the strength of the magnetic field but also the polar angle and the azimuthal angle, which describe the direction of the magnetic field, are found to affect the stability of SkX. Moreover, they reorientate SkX at certain conditions. Our findings pave a way for the manipulation of SkX.
