How to reduce the size (in MB) of pictures inserted in a PDF?

Question

Hello,

I'm writing a Master thesis when I need to include several photographs, but I've got a problem with the size of the generated PDF: 18MB, which is more or less the cumulated size of all the picture included.

How can I tell Latex not to keep the original picture and reduce it, but to shrink the picture before including it in the PDF?

I use \includegraphics[height=6cm]{img/cinema.jpg} to include my figures.

Thanks

Answer 1

You need to reduce the size of your pictures yourself before you include them (with software of your choice). That's the simple solution.

I think the rationale for including in full is that PDF is a vectorial page description language, and you might want to render a page at an arbitrary resolution later.

Answer 2

You can use primoPDF to downsize all pictures at once, after you created the pdf in Latex.
