Default Reduce size of .pdf "graphic"

I have a friend in real estate who sometimes blindsides me with a question that I assume (wrongly) that I can answer right away. This time, he has a plat that he's scanned and wants to include with other parts of a .pdf document to email to another agent. His original is about 508KB. Apparently they want this particular page to be 300KB or less. I smugly opened the page in Adobe Acrobat and clicked on File-->Reduce File Size...

There were no choices except for what version of Acrobat to convert in. OK, I did it. The reduction was all the way down to 488KB! Why bother? Is there another way I can do this? Some other application?

EDIT: If it helps, I have a copy of the pdf at http://thebaldwins.com/platorig.pdf

Thanks,
Linda

This is scan data, you need to modify it in PhotoShop or something similar.

You have a scan of a black and white image that is stored as an RGB image. Just changing it to a greyscale image will make the file 1/3 of its current size.

Don has the right idea, change the image to black and white. Maybe your friend can scan it again in black and white to start out, perhaps avoiding some loss of quality.

Also, sometimes using an earlier version of Acrobat can reduce the final PDF size, as may using different PDF software. My experience with those techniques have been limited to MS Word documents, which may not apply to images. You don't have to buy the software, as some web sites do it for free, and some have trial versions of the software.

Welcome back, Linda, LTNS.

Default How's this look?

I just did the standard Acrobat PDF optimizer. It looks pretty low-res, but then so did the original: I expect you could improve on it by playing around with the settings in Acrobat 8 Pro.

I got it down to 18 KB, by a more round-about route:

1) Opened the PDF in Photoshop
2) Converted from RGB to Grayscale to Bitmap (24 bit color depth to 1 bit color depth)
3) Saved as a PNG file
4) Opened the PNG file in Acrobat and created a PDF from it. (Acrobat/File/Create PDF/From file...)
5) Ran PDF Optimizer (like Robin did), using the default settings.

Looks worse than the original, but still readable. Robin's less processed version looks better--I'd go with his method, unless you want a REALLY small file.
