JPEG-compress embedded images in PDF

Is there a printed Inkscape book...

Greetings.

The PDF files generated by Inkscape are unacceptably large when the document contains bitmap graphics. (An A5 book cover I just did is over 33 megabytes -- far too large to publish online.) I presume this is because Inkscape is embedding raw bitmaps into the PDF file, rather than using JPEG compression.

Is there a tool which will postprocess a PDF file to convert the embedded bitmaps to embedded JPEGs? I would prefer something free (GPL or the like) and available for GNU/Linux.

Regards, Tristan

I dont no such a tool, sorry. Perhaps you may work around the problem by using OpenOffice.org to generate the pdfs. If you import an image to OOo make sure you "link" to it. So you can reexport the image with inkscape if you chaned something and dont need to reimport it in your openoffice document.

You might try pdftk. I don't know if it has recompression capabilties, but it's got quite a few capabilities for re-processing PDF files.

Or build your PDF in Scribus, I hear it's PDF-oriented. I'm pretty sure there are cli tools to extract images from PDF files and they can then be imagemagicked, but getting them back *into* the PDF is not something I know about.

I just discovered a tool which does what I want: PStill http://www.pstill.com/. It is available for several platforms in command-line and GUI versions, though it is not free software.

I still think that there must be some way of doing this with Ghostscript, but I haven't as yet figured it out.

I've got that (one of my favourite programs, in fact); it doesn't transcode embedded images.

And what about printing to pdf? In PDFCreator I believe you can set compression ratios and the like? So no "export" to it, just PRINT to PDF?

PDFCreator is available from sourceforge.net, although I'm not sure if it is for non-WIN platforms.
