Uses the Neural Filter to increase its size5. Save and close to transfer changes to the PDF. But as already said, there's a limit: generating extra pixels is never very good quality.

@german_3779 Increasing the quality of an image that has already been created is limited—you would be better to go back to the original and save it as a high quality PDF. You could try re-saving it s a high-quality PDF, but if the files within the file like images and vector artwork was saved as a smaller sized PDF, chances are it will be a low quality too. For example, you can have a car that is a Yugo or Pinto, and you can't snap your fingers and make it into a Ferrari or Aston Martin.
