Subject: Re: Converting overlarge PDF scans
Hi,
For the past three years I've been running an action in Adobe Pro to reduce
file size on scans of our lab notebooks. We send our books away to be
scanned by an external company, when they return the pdf is approx. 200 -
300mb in size, (The books are 200 pages of A4). Once I run the reduce file
size action the output pdf is generally between 20 -40mb. The images
contained in the books are still legible although not of print quality,
however as a reference point our scientists seem to be fairly content with
the output.
I've scripted this to run across multiple files at a time, it generally runs
without a hiccup.
Cheers
Colin

As Tim said, if you have Adobe Pro then it will reduce the size of all files
in a folder:

You can also use the "Action Wizard" in Adobe Pro to export images as jpg or
png and then compress them. I've had good results using TinyJPG:

This software also claims to do the same (untested by myself though):

Good luck

I have a large number of historic papers that appear to have been scanned as
bitmaps and then presented as PDFs. The result is files that are around 30mb
and upwards to 100mb in some cases. Does anyone know if there is any way
these can be reduced in size?
