Save document as jpeg or png

No.

You can export to PDF. Then open the PDF in Preview, and with thumbnails enabled, select each thumbnail, and then File menu : Export... — choosing your .png or jpeg output format for the specifically selected PDF page.

It is also possible with the optional installation of Ghostscript to process a single PDF into a sequential (by page number) color, or grayscale .png documents with a choice of resolution.

One can open the Pages document, and File menu : Print : PDF : Save PDF to Folder as JPG. However, this just does the conversion, and the output files are shoved into $TMPDIR as pdfname.jpeg, pdfname 2.jpeg, etc. You will have to launch Terminal, and type: cd $TMPDIR. Then ls *.jpeg. You can then do open pdfname.jpeg and Preview will open the file.

Menu > File > Print > PDF (bottom left corner) > Save PDF to folder as jpeg

This will do 1 page at a time.

Do you really need jpeg or png? PDF is much sharper and frequently smaller.

Yes you can. Have you tried?

If the PDF is vector it will be absolutely sharp, unlike the jpeg and png.
