I am using Adobe Acrobat 5.0 and have a huge problem.  I have scanned
in a 24-page magazine article -- which features full-page color
pictures -- to send to a colleague as a .pdf file.  However, the file
size is HUGE (100MB) and I cannot figure out a way to create a smaller
.pdf file that I can e-mail that will retain the color photos, et al. 
Can anyone help?

I can't even ZIP this thing!

If you still have the original magazine, you will need to rescan the
article after you set the resolution for graphics to a lower level.

Please note that if you have done full-page scanning, then most likely
the entire page is a graphic as far as Adobe Acrobat is concerned.
That would explain the size of the file, as 10 MB / 24 pages is
approx. 417 kb per page. If you set the resolution down to, say, 150
dpi or lower, the page will be a bit fuzzier, but the file size should
drop. Keep playing with the resolution until the file is small enough.

Also, consider splitting the article into separate files for ease of e-mailing.

Can you confirm what your resolution setting is for graphics in your
Adobe Acrobat settings?

I can believe it, and sorry for misreading your original post, that's
100 MB, not 10 MB you wrote... meaning over 4 MB per page!

Please confirm/try the following:

- Resolution set to 72 dpi (for screen viewing only)
- Graphics stored as JPEG

You may also want to consider finding a different way of getting this
article to your friend. Does the magazine happen to have an online
version?

When scanning in a full page as a graphic, even at 150 dpi it is a
1275x1650 graphic. That's 2.1 M pixels, so at 16-bit color it's over 4
MB per page. at 72 dpi, 16-bit color, it will still be 970 kb per
page, or 24 MB for the whole article. The only way to get it smaller
while still usable would be to convert the text into electronic text,
and only scan in the pictures as graphics. That's a lot more work.

Hi prpro,
I just found this program called PDF Enhancer ( For Windows and Mac OS X ):
URL: http://www.apago.com/PDF_Enhancer

On a PDF ( 100MB ) File I tested PDF Enhancer on, it reduced the file
size by about 92%.
PDF Test FIle URL availabe at:
http://poseidon.uprm.edu/p-reports.html

I should add that I Enhanced the File using "Web Enhancer" and I was
also able to zip this file
but not by much ( 11% ).

I hope this helps.
If you have anymore questions, please don't hesitate to ask.

Thanks again.

That PDF Enhancer really did the trick!!!  Thanks SO much for finding
this -- I never would have thought of a third-party app.  I decreased
my file down to 2MB! Thanks aht and googleexpert!  And deepak, I'm
opening my Yahoo Briefcase right now!

Hi,

In addition to the answer, if you have internet connectivity, you can
upload the .pdf file to a website like http://briefcase.yahoo.com. You
can then send a link to the uploaded file to your friend on e-mail. He
can click on the link and download the file.

I mention this idea since even if you reduce resolution etc, you will
end up with a file size of at least 5 MB or more - most e-mail
programs have problems handling large attachments.

Hope this helps
Deepak
