Run your assembled PDF through Acrobat
Distiller to reduce its file size. In Acrobat 6, try PDF
You started with two or three PDFs, combined them, and then
cropped them. Before going any further, consider running your
assembled PDF through Distiller. This refrying
can reduce duplicate resources and ensures that your PDF is optimized
for online reading. It also gives you a chance to improve your
PDF's compatibility with older versions of Acrobat
and Reader. In Acrobat 6, you can conveniently refry a PDF without
Distiller by using the PDF Optimizer feature. Even so, distilling a
PDF can yield better results than the PDF Optimizer can.
Traditional Refrying with Distiller
Refrying traditionally has been done with a
simple hack, reprinting the PDF out to Distiller, which creates a new

function. Acrobat will consolidate its resources as much as it can.
Acrobat 6 does this more aggressively than Acrobat 5 does.
Open the Acrobat Print dialog (File → Print . . . ) and
select the Adobe PDF printer (Acrobat 6) or the Distiller printer
Set the Distiller profile by selecting Properties → Adobe
PDF Settings and adjusting the Default Settings (Acrobat 6) or
Conversion Settings (Acrobat 5) drop-down box. For online
distribution, consider these profiles: eBook, Standard, Screen, or
Smallest File Size.
If you cropped your PDF, you should set the Print page size to match
your PDF page size. In the Acrobat 6 Print dialog, adjust Properties
→ Adobe PDF Settings → Adobe PDF Page Size to fit
your page. Use the Add Custom Page . . . button if you
can't find your page size among the current options.
In the Acrobat 5 Print dialog, adjust Properties → Layout
tab → Advanced . . . → Paper Size to fit your page.
Select PostScript Custom Page Size if you can't find
your page size among the current options.
Print to Distiller. Do not overwrite your original PDF.
Review the resulting PDF. Is its file size smaller? Is its fidelity
Reapply page cropping as needed. You might need to rotate some pages.

Refrying with PDF Optimizer in Acrobat 6 Professional
PDF Optimizer (Advanced → PDF
Optimizer . . . ) performs this service much more conveniently. Its
settings resemble Distiller's, and they enable you
to downsample images, remove embedded fonts, or remove unwanted PDF
features. You can also change the PDF compatibility to Acrobat 5.
Click OK and it will create a new PDF for you. Compare this new PDF
with the original and decide whether to keep it or try again. The
best time to use the PDF Optimizer is just before you put the PDF
To simply make your Acrobat 6 PDF compatible with Acrobat 5, select
File → Reduce File Size . . . instead of the PDF Optimizer.
The Best Time to Refry Using Distiller
The best time to refry a
PDF using Distiller (as opposed to the PDF
Optimizer) is after you have assembled it, but before you have added
any PDF features. Here is the sequence I typically use when preparing
a PDF for online distribution:
Assemble the original PDF pages and Save As . . . to a new PDF.
If page sizes are wildly irregular, crop them [Hack #59] .
Refry the original PDF document and compare the resulting refried PDF to the original. Adjust Distiller settings [Hack #42] as necessary and choose the best results.
Crop and rotate the refried PDF pages as needed.
If the original document had bookmarks or other PDF features, copy them back to the refried PDF [Hack #61] .
Add PDF features [Hack #63] or finishing touches [Hack #62] .
Save again using Save As . . . to compact the PDF. In Acrobat 6, save
the final PDF by selecting File → Reduce File Size . . . and
set the compatibility to Acrobat 5.
