Large pdf size

[demirci]

When I convert 7 tiff files, each 1 MB, the resulting pdf is 70 MB.

What is the reason of this?

perhaps set the density you want for your pdf files and see if that helps. also use -depth 8 if on Q16

Perhaps it's the compression setting - use e.g. "-compress zip" or "-compress jpeg" (see here).

Drarakel thank you. The link was useful.

By the way, -depth 8 does not help. It becomes even greater. -compress jpeg is also not good. (I think that is because I was converting from a BW tiff file.)

-compress zip is working very well for BW tiff files.
