TIFF to JPEG conversion kills dpi
#2
Think of a triangle.

At one apex you have a digital image. Size is measured in pixels.

At the second apex you have a printed (ie on printed on paper) image. Size is measured in inches.

At the third apex you have dpi. Used when determining print size for a digital image.

Given any two, you can calculate the third.

You are only working with digital images so the important thing is the image dimension in pixels. In a digital image the dpi is just a dormant value, only used when calculating print size (which your are not doing).

In Gimp, go to
Image > Print Size...
You can change the dpi there. Watch the print size change as you do this. The image size in pixels does not change when making changes here.
