300dpi images in a PDF need to downsample to 72dpi. Is this possible?
Vineet Singh
I have a couple large (20+mb) documents that are in PDF format. They
are technical manuals with a large number of 300dpi pictures. They
print great, and are easy to work with, but are WAY TOO LARGE to make
available through a www site/server.
Is there a way to take an already made PDF with numerous 300dpi images
in it, and convert it to a MUCH smaller "image" downsampled PDF file?
300dpi PDF --> 72dpi PDF (screen resolution).
This would be really awesome if I can do this. I thank you in advance
for all your replies!
I have ACROBAT 4.0(5?), and also ACROBAT 2.02. I also have DISTILLER,
but I don't think it will do what I need.

If you don't mind a commercial solution, take a look at our plug-in

Aandi's being polite and modest. AFAIK his software
is the *only* product that will do what you want.

Sure it will. Just print the files out from Reader and distille them
again, with "Optimize for screen" setting.

However, I tried the demo version of the plugin (acrobat 3, exchange),
and it seems to work well, if not really slow.
However, I was expecting a much smaller file. I took one of my 1000+
page PDF's and cut it down to 500 page. The resulting OPTIMIZED, 300dpi
PDF was about 22mb.
I ran your plugin (that puts the X over each page), and although at
72dpi, the graphics really suck (not your fault), the file size only
went down to little less than half (9mb). This is still too large. At
150dpi resampling, the file is at 11mb, and the pictures are readable
still.
If I register the plugin, and it gets rid of the "X", will that make
the files smaller? (since each page would not have the "X" in it)? Does
the X take up a lot of space when it's done on each page?
I like it, I just wish it was faster (and I'm on a pIII 733! :)
Now I'm leaning on trying to convert the PDF files to HTML... but
everything seems to stick my nice PDF's in a blender, and then you can
see the mess in your browser... not pretty or readable, or even useful.
PS: All the graphics in my original PDF's are BITMAP, and only 2 colors
(black and white). No grayscale or color at all.
Thanks for your help!

Now how, or what do I print TO? print the entire PDF to what printer,
and then how do I distill it again? I was kinda hoping this was a
solution, but I tried something similar, and DISTILLER said you cannot
DISTILL PDF FILES... Damn it! :)
Thanks!

Print it to a generic postscript printer (to file). Then distill the
resulting PS file with your desired settings.
Distiller converts PS files to PDF files.

PDF files are made from PostScript files. These are created by capturing
the printing commands that normally go to the printer, to a file.
Special capturing software can do that, or a printer driver can be
configured so that when you start printing, it asks tou to select an
output file. That file is then opened in Distiller, which converts
("distills") it to PDF. Distiller can not do anything to existing PDF
files.
So, the idea is to print the PDF files from Acrobat Reader to create
PostScript files, which can be converted to PDF files with Distiller. At
least under Windows, if you pick the right printer driver (most likely
named Acrobat Distiller), it creates a PostScript file on your hard disk
and the automatically converts that to PDF.
I have never seen Distiller under a Mac, but I guess it has a similar
system.

Really, not very much at all. It is compressed.
If it only reduces this much it might be that the graphics were
previously reduced in resolution by Distiller, and are not still at
300 dpi.
Check some images with the INFO function in Box Of Tricks to find that
out. Also remember that you can adjust the quality and resolution in
Box Of Tricks.
If you can redistill it should produce comparable results. Most but
not all files can be.
Jennifer Nicholls
your job options (ctrl+j) and click on the "Compression" tab. There you can
tell Distiller to downsample your images to 72dpi and compress it with JPEG
in whatever quality you need and to compress text and line art. Also, make
sure that on the "General" tab you have "Optimize PDF" checked. I think you
will find that by using these options you will have a much smaller file.

with a 72dpi setting? Works fine and is cheap. O.k. you might loose some
info like bookmarks etc. - _if_ there is info like that in the PDF...
Ciao.

Thanks Michael.
I've tried all the suggestions presented to me (thanks everyone!),
however, they all have problems, ranging from severe to impossible to
work with.
Aandi's is probably the best solution, but I don't have 200$ to spend
on something that is just an idea, and will not generate any income for
me.
The printing to PS (.prn), is half-assed in my situation. At first the
Adobe PS printer driver conked out at 256 pages. With Aandi's
suggestion, I downloaded the latest iteration of it from adobe.com.
Awesome right? No, it make a nice .PS file of my 1000+ page PDF, that's
all good... now Distiller can't seem to handle "distilling" the
large .PS file to a PDF.
After about 340 pages, it terminates with a weird error (I have 196mb
of memory, and 2gb free on my swap drive). Something pertaining
to "ignoring EOF, contents flushing" and no PDF file was generated. I
have 9000+ pages to process, and with such a flakey conversion process,
I don't have the determination to attempt it.
Oh yes, I also loose all the bookmarks. It wouldn't take me FOREVER to
put them back, but it seems like it WILL take forever to convert first
to a PS, and then back into a downsampled (150dpi looks good) PDF.
At this point, even Magellan's PDF to HTML (bcl-computers.com) option
sucks. It works well, but not for my PDF's. I have many "capture
suspects" I think, and it ends up creating ALMOST right looking "HTML"
files, but then I look through it more, and find nearly every page has
way too many areas where the text is "doubled" and off.
What I mean is, lets say it says "MANUAL" (as a font), well right above
and to the left, it "says" "MANUAL" again! (this time as a picture!).
It's offset, and looks really bad, and it happens everywhere.
I give up :). I can't justify spending $200 for Aandi's product (though
it seems like it would do the job), and $200 for Magellan's "PDF2HTML"
product is way too high for such "artifacty" output.
Thanks for all your help guys/gals. This is why I love the net :)

This symptom sounds like you have used "fake bold" in creating the
document. That is, you have applied BOLD to a font which does not have
a bold version installed.
What happens then can be very messy. You may have the same letters
written twice, slightly offset. Or the same letters printed normally,
then as an outline. A program trying to convert to some other format
can only struggle with these, since the two (or more) copies of each
letter are now completely independent of one another...
