Help! PDFs

[Hank Zangara]

I received a huge pdf document (750k) that needs to be reduced in file size for web-posting.

So, I opened in Photoshop, discovered it was 300dpi, converted it down to 72dpi, and re-saved as a Photoshop .pdf.

Turns out to be way BIGGER (1.5MG) file size than the original!

What happened? And how can I otherwise reduce the file size of a monster .pdf?

You think 750K is HUGE? Oh dear - I'm working 4.5MB files that get posted to the web. And that's smaller than they were.

All you did was change the DPI? Well, that won't actually change the
file, I don't think. If you want to make the image(s) smaller, you have
to resample them, which means changing the number of pixels rather than
changing the DPI. Correct me if I'm wrong, but with DPI, the number of
pixels will remain the same - only the appearance of the image will
change. But still, even just changing the DPI should have lead to a
file of the same size. That said, maybe PSE resampled the images and
stored more information, or maybe it stored font information that wasn't
in the original (which can sometimes make a big difference).
