Need to downside a PDF but it won't get any smaller

[sarap33634054]

I have an indesign project that is about 13-16MB.  I'm gone through and decreased the size of all the jpegs so they are all under 500mb in the file.  I have a few pdf's in the file that are 500-1,000 MB. When I export, I have it set to downsize to 72 PPI but I have the quality set at maximum.  If I decrease that too much, than the quality just isn't as good.  When I do all of that my PDF is still about 7MB.  From there I've optimized the PDF and I've also tried to reduce the PDF size and that only gets it down to about 6MB.  Is there something else that I'm missing.  I've looked at some settings and it shows that my content streams are about 50% which is the same as my images.  Is there something I can do to decrease that.  I basically have text, some arrows, lines, and a table in my document and then the rest is jpegs and a few pdfs.  Are the arrows/lines causing that high content stream or would it be the PDF's inside the document.

There is a limit to how small you make a file. If the PDF optimizer in Acrobat can’t do any more, then you’ve reached that limit.

smallpdf.com seems to shrink my files when my standard routes can't do anything.

If you want to make your InDesign document smaller, do a save as. I don't know if a smaller InDesign file makes a smaller PDF.

I know I should have checked first before posting, but I might not get back to this for a bit.

In this case, Save As reduced the size by 3.3 MB

More options to play with—enable Optimize for Web View and remember that the higher the Compatibility, the smaller the file. A same file saved for 10 or later is file is smaller that an Acrobat 9 file, which is smaller than an Acrobat 6 file. You can only get so far in InDesign, so try File > Save as other > Reduce File Size in Acrobat.

I know this is "old" but thanks fo the golden advice! Brought me from 8MB to 1.2MB.

Thank you 🙂

I'm having the same issue. It is utterly incomprehensible that this is so complicated. i just want to be able to email a smaller verion of the pdf. unreal.

I know this is an old thread but I'm having a TERRIBLE issue with this as well. I have a 1 page PDF document that I can't get to shrink no matter what I do to it in Photoshop or Acrobat. "Reduce file size" wont work, Were you ever able to get yours resolved? Any tips for it? Thanks!

Thanks Jeepgirl...that tip of your reduced my 10.9 MB pdf to a 459k pdf...cheers!

I was also having no luck with reducing file size, however as a last resort I just exported a large PDF to Powerpoint and then exported the PPT file back to PDF and reduced it from 16MB to 1.6MB.

I am always leery of running any document through the MS Office tools — perhaps less so with Word, but PP has never been anything but a layout and file management nightmare that makes CorelDRAW look stable. 🙂

I just duplicated your effort with a PDF document at hand, and it went from 292k (original, reduced-size PDF) to 126k PPTX to... 398k PDF.

I suggest that only careful management of the export to PDF from the source tool and then Acrobat's reduce file size feature can produce a PDF that is minimum size, maximum stability/compatibility and acceptable quality. After all, if an "outside" tool can reduce the image sizes and overall data set, tools with more control over the components and process should be able to do it better.

I expect mine was an edge case, to frame it I scanned a 24pp document with ScannerPro on my iPhone, output to PDF, couldn't get it down more than 3MB using reduce file size (on a Mac).  Last resort tried exporting to other formats and back again, was pretty surprised this worked!  Not for everyday, but thought I'd share my experience, as reduce file size didn't work this time (it usually does).

[James Gifford—NitroPress]

On the one hand, whatever works in a situation like this, works... and Yay!

I'd just be cautious about using this process for anything client-critical; passing along a PDF that's acceptably small but might break in a number of ways for clients or downstreamers is something to avoid.
