Over here, I get 155 KB and 152 KB, respectively Clipped vs Print/Saved – same article at the link you posted.
There are differences. “Clipped” version is smaller point size and had two blank pages appended at the end. Deleting these caused the file to get 2 KB bigger ( go figure). “Print/Saved” version is more readable and no extra pages
Apparently the Clip to PDF page version is 143, but the Clip to PDF (not paged) is 540-550. Strange, I would have figured the form without page break would have less formatting changes, and thus not increase in size. Is this as it should be? Thanks
