Pajou moved between the decorative style of the Rococo and the strict logic of Neoclassicism. His work often features mythological figures like Mercury or Pluto. He focused on anatomical correctness and physical tension. Pieces such as Fickle Love and Faithful Love show his ability to capture human emotion through small marble statuettes. He preferred clear forms and balanced compositions. His portrait of the painter Hubert Robert shows his skill in capturing the likeness of his contemporaries with directness.

Modern collectors value the clarity and technical precision found in the work of Pajou. His drawings and sketches, such as Head of a Youth Turned to the Left, offer a look at his process. Prints of his sculptures provide a sense of three-dimensional form for a wall. The X-radiograph studies of his busts reveal the internal structure and craftsmanship of eighteenth-century art. His work brings a sense of classical order to an interior.
