PDF file too large...X Object Forms?

[evac15315126]

My InDesign file is 5mb.  When I export it to a PDF, it becomes 80mb.  Compressing the file didn't work because it is too large.  I don't think it is the images in the document--when I used the Optimized PDF function with Adobe, much of the issue was "x object forms" (taking up 90% of the file size).  Any thoughts?

I would be very happy to learn a lot!

Please teach me and all of us.

Others know that already so it would be just for you - 

vector graphic offer scalability - bitmaps don't.

It's not InDesign's fault that your vector file have to many objects.

Sometimes, vector will be much smaller than a bitmap - for example a national flag... 

So don't be a smart ...

I read your other answer and perhaps there's something for you to consider as well...

In this particular instance, my task was to create a small-sized PDF.

The vector original file is still around and if there's a need to make an A1 or A0 size poster, the scalability is still available to me by linking back to the .AI file.

You've never stated that it was the main goal / priority over quality.

If your document is destined for phones / e-books - then yes, low res JPG is fine - but you've not stated this...

By default PDF is for printing...
