I created a 33 Page PDF file in InDesign where I placed PDF files of AutoCAD drawings and some images. When I export it as the Smallest file size pdf, it saved 13 MB filed, which is to large. It is supposed to be less than 5 mb.
What do you mean you created a PDF file in InDesign? InDesign can export its own file type (InDesign documents) to PDF, but you cannot ‘create’ a PDF file in InDesign. And how do you know it’s ‘supposed to be’ less than 5 MB? If the images are large, 13 MB may as good as it’s going to get without completely butchering image quality.– Janus Bahs JacquetMay 30, 2021 at 17:37
Why do you see the file size as too large? Is it because the exported PDF is larger than the sum of the placed PDFs and images?– WolffMay 31, 2021 at 16:15
I have also worked with Autocad-generated PDF's (line art type of real estate projects). I know these Autocad PDF's are artwork-heavy and generally much larger in size than what we're used to from using Illustrator artwork. For some reason Autocad saves these PDFs in a more complicated way by breaking down the artwork into smaller sections generating a lot of micro-objects.
I found no way to compress the end result, other than to save the Autocad file(s) as raster images, hi-res if needed, and then, there is some control of the resulting file size by playing with InDesign's export settings.
Autocad can do nontiled files if you ask it to.– joojaaMay 30, 2021 at 19:49
You probably know better than us, but in some cases the Autocad work is done by third parties (architecture firms) and you don't have a direct control over that process. You just get the PDFs to use them in a presentation and these guys in real estate, they don't like delays.– LucianMay 31, 2021 at 7:31
Well its usually archicad that's making the trouble. If it was me i would tipple the price for architects. I had to print a pds that had a hunndredthousand lines, but the catch the same document was in a clipping mask 40 times for 4 million lines total. WTF.– joojaaMay 31, 2021 at 10:35
