Is this feasible?

I'm dealing with a number of pdf's. While I can read pdf's easily
enough on screen, if I crank up the zoom, the printing size in pdf's is
terribly small. (Particularly when you're trying to distinguish
cuneiform signs.)

However, I can use pdftoppm to switch the pdf to a list of ppms. ppms
take up a large amount of space, and are a little difficult to fool
around with. So, using optipng, I batch-convert them all to pngs, which
need a lot less memory, and can (usually) be increased to a usable size.

So, what I want to know is, is it feasible to run pdftoppm (on a 50-200
page pdf) and pipe the result into optipng to change it into pngs in one
total operation? Or would this do such things as using so much
resources that my machine would freeze, or send error messages such as
"Error- Idiot operating the computer. fetch sane person and try again."

Of course, the second thing is, if this is feasible, what would one put
into the terminal? This is all Assuming that I operate from the same
directory as the pdf I'm attacking.

Thanks,
