Turn Any Photo Into a Pencil Sketch

Upload a reference image and use image-to-image generation to translate it into a pencil or charcoal sketch while keeping the original composition intact. Adjust the style strength to control how much of the source photo is preserved, keeping faces or key details recognizable as the AI strips color back to expressive lines and tonal shading.
