TIFF to JPEG conversion kills dpi

[TheBrassGlass]

Yes, I can confirm that when I download it from the cloud site, it is at 300 dpi. In fact, saving it as the GIMP native file (.xcf), it is still 300 dpi. But if I export as JPEG, it becomes 72 dpi. I do not understand why this is.

I will try doing as you say with print size.
