Saving Powerpoint illustrations as high quality image files

Download GIMP and File -> Open
In the advanced Open options you can specify a suitably high dpi rate
Then save out as a JPEG with the least possible compression
Ok tried Gimp, but images are still poor quality (pixellated somewhat when zoomed in). In the advanced Open options you can specify a suitably high dpi rate
Then save out as a JPEG with the least possible compression
What specific values should put in for the following:
width
height
resolution
PS: when I try to increase the values and click open, the computer crashes!

Saved as PDF and is very high resolution!
How are you measuring resolution? What makes you think that it is "very high resolution"?Publishers don't expect you to be a professional graphic designer. So if you speak to them and explain the problem, they can advise you as to what you need to send them. Powerpoint presentations are the bane of the professional printer's world, so they can advise the best way to get a print-quality output from your application. They've had all this stuff before.

That's actually a question for your journal publisher. For instance, if you were looking at a column-width illustration in Nature (3.5" half-page column) at 1200dpi you'd want a width of 4200 pixels. The height should adjust itself automatically in proportion.width

If it's crashing it may be that you need more memory. I'm a Photoshop user, but just downloaded GIMP into a Win 10 VM with 8Gb memory and opening a PDF in GIMP at this res works fine.
