I don't know if you can remove elements with Acrobat, but it could be possible to work with the uncompressed PDF like this:
Uncompress the PDF with pdftk (a single page in this example):
Code:
pdftk rudyard_kipling_2004_9.pdf cat 3 output a.pdf uncompress
Now edit the a.pdf file with a text editor. Near the end you'll find:
Code:
18 0 obj
<<
/Length 4339
stream
After that, comment out the first two BT...ET blocks (page footer and page number) and the following lines until the next BT, like this:
Code:
%BT
%/F3 8 Tf
%15 25 Td
%0 -8 Td
%<005A005A005A00110033005200480050002B0058005100570048005500110046005200500003001000030037004B00480003003A00520055004F0047000A0056000300330052004800570055005C0003

%BT
%/F3 8 Tf
%15 25 Td
%576.914 -8 Td
%<0016> Tj

%ET
%10 10 m
%10 782 l
%602 782 l
%602 10 l
%10 10 l
%h
%S
Since that's 21 lines (and 21 additional % characters) you have to add 21 to the length:
Now you can compress back the PDF:
Code:
pdftk a.pdf output b.pdf compress
And the resulting PDF is attached.
