I have a long paper in which all of the pictures I drew and put them in the document as .pdf.
Is there a way to protect these images from copying by conversion to image formats such as (.jpeg, .png, etc.), i.e. lossy formats? When I make presentation in Keynote, there is an option to "print all images as a preview", which converts them all in such way. Is there something like that in Pages or can I somehow convert these image after I export the .pages file as a .pdf?
Please note, that I don't want to convert the whole .pdf to image as I would like the text to remain vectorized for better readability as the footnotes are written with small-sized font.
