Here goes:

Code:

k2pdfopt.exe -i Single.page.source.pdf

PDF VERSION:    1.3
PAGE SIZE:      5.81 x 9.18 in
PAGES:          1

       Page       Ref           Details
Mediaboxes (1):
        1       (3 0 R):        [ 0 0 418 661 ] (5.81 x 9.18 in)

Fonts (1):
        1       (3 0 R):        Type1 'Courier' (5 0 R)

Images (2):
        1       (3 0 R):        [ Flate DCT ] 996x1575 8bpc DevRGB (6 0 R)
        1       (3 0 R):        [ JPX ] 872x1379 8bpc DevRGB (7 0 R)

I played with the different settings, but the only option that compressed the page further is the following… which, unsurprisingly, makes the page harder to read than the original:

Code:

k2pdfopt.exe -mode copy -bpc 1 -c- Single.page.source.pdf

I'll settle for GhostScript and its ~15% compression, or learn how to rip the text layer and turn it into an EPUB.

Thanks!
