storing images as jpeg instead of png?

[MichaelH]

It looks like ON stores pasted images internally in png format (that's all it
will save them as).

Is there any way to get it to use jpeg? I don't need lossless compression
with most files I paste in and could benfit from the savings in disk space
used.

I don't have a straight answer to your question, and forgive me for asking,
but in these days of affordable 500GB and 1TB hard drives, how much do you
hope to benefit in terms of disk space from using JPG images in OneNote?

Actually, if you're doing lots of screen grabs, PNG's are often about 10
times larger than JPG's. A full-screen png on a 1280x768 monitor is about
1.2 MB vs 150 KB in the un-scientific test I just did. Personally, my tablet
only has an 80GB hard drive but I also like the lossless quality of PNG's
enough that it doesn't bother me.

Another thing, if you print to OneNote, I believe the files are actually
MDI's (Office Document Imaging which are like highly compressed TIF's)
although they look just like inserted images. I could be wrong on this of
course, because I don't remember where or why I came to that conclusion.

Josh is right, png (and most tiffs) are 8-10x larger than their jpeg
equivalent, even with low (10%) jpeg compression.

Drives may be affordable but I use ON with a tablet PC and regularly sync it
with my desktop for backup purposes. The images I grab are taking up a lot
of unnecessary space that also increases the time needed to back up the data.

I can understand ON using lossless compression by default. I wouldn't want
compression artifacts to interfere with text recognition but for an image
that doesn't have text I'd much rather it be as small as possible.

Fair enough.
