The implementation of shortcuts to adiabaticity (STA) enables a substantial reduction in the evolution time relative to traditional adiabatic methods, concurrently mitigating detrimental environmental interference. In this manuscript, we present a protocol using STA for the one-step generation of squeezed-light states of arbitrary photons. By starting from different initial Fock states, high-fidelity (>0.99) squeezed-light states can be generated with the same control Hamiltonian. We investigate the protocol's robustness under conditions of systematic errors and environmental noises through numerical simulations, which confirm the feasibility of the proposed scheme. The protocol may facilitate the investigation of quantum state control process, with the potential for significant impact in the near future.
