Compress/Optimize a PDF document

[MountainX]

I have a 600MB PDF document that I need to get down to about 10MB. The last time I did this I used Adobe Acrobat Pro 8.0 on Windows. It has some automatic optimization functionality that will reduce the size of a PDF. How can I accomplish the same thing on Ubuntu?

P.S. Should I post this in another section of the forum?

Thanks.

If I was to take a guess at this (because I know very little about the pdf format or compression methods), I would say that you'll have to buy something from adobe to get that good of compression on a pdf file. I guess this because pdf is not an open format but is owned by adobe.

If this file contains pictures, then there is probably little you can do.
But if its only text, you could export it to a text file - sure it would lose much of the formating, but the information would be kept.

In Windows I know of a very good program that can do this: Abbyy PDF Transformer...

KPDF (kprinter dialog) allows you reprint files as pdf (change image resolution etc). Some people tends to paste horribly big resolution images into their documents.:(
