[NABS-L] PDF Question

[Vejas Vasiliauskas]

Hi all,
I recently received a large PDF for one of my classes in the form of an image. Usually, with image PDF's I convert them with Robo-Braille. This one, being 256 pages and about 37 MB, was too large to convert.
Fortunately in this situation, I found another accessible version online for what I needed, but in the future, for large PDF's, I was wondering if anyone knows of an app or Web site that would either convert the file, or at least reduce the size so I could send the email.
Thanks,
Vejas
