His technique relied on a precise application of dots and short strokes to create soft tonal transitions. This method allowed him to replicate the smooth textures of oil paintings, particularly in skin tones and fabric. When interpreting works by masters like Raphael or Titian, Godefroy prioritised clarity and structural accuracy over decorative flair. His version of Balthasar Castiglione demonstrates this focus on form. He avoided the harsh lines common in traditional copperplate engraving, preferring a subtle approach that mimicked the atmospheric quality of the original paintings.

Modern collectors value Godefroy for the historical weight and technical precision found in his prints. His works act as windows into the aesthetic preferences of the early nineteenth century. The monochromatic nature of his engravings makes them easy to integrate into contemporary interior schemes. They provide a sense of classical order without the visual clutter of more modern styles. Because he chose to reproduce some of the most famous compositions in art history, his prints offer a way to own a piece of the Western canon in a refined, graphic format.
