Compress pdf-file

Hello,

I have scanned a document and saved it as pdf-document with xsane.
The size is 17.6MB

I can not compress this pdf document, it seems.

I've tried the zip command, but it stays 17.6MB

Code:

zip IN in-A.pdf

I've tried pdftk, but it stays 17.6MB

Code:

pdftk in-A.pdf output in-Aa.pdf compress

Code:

-rw-r--r--. 1 root  root  18M 2011-04-06 16:59 in-Aa.pdf

-rw-r-----. 1 Jonas Jonas  18M 2011-04-06 16:21 in-A.pdf

-rw-rw-r--. 1 Jonas Jonas  18M 2011-04-06 16:44 IN.zip

How can I reduce the file size ?

I would assume that your image is a JPG embedded inside the PDF. So the next time I would directly scan to JPG and choose a resolution/DPI-value that will give you a smaller size. For now you have to extract the JPG from the PDF to compress it.

Or convert to text.

Try

Code:

zip -9 IN in-A.pdf
