You could as well go to the Scale dialog, set the desired print resolution and the desired print size in physical units and click OK.

[Gimp-user] Increasing DPI of image
Can Gimp increase the DPI of a PSD file without affecting the physical dimensions of the image? We have a wedding invitation in PSD that is 72 DPI and the printer needs 300 DPI.

We have a wedding invitation in PSD that is 72 DPI and the printer needs 300 DPI. Thanks in advance. You need to scale your image up to 300/72 (~416.6%) of it's current size as well as setting DPI to 300. To understand why, you need to realize that your original question is like asking 'How can I make this small while keeping it big?' -- DPI is literally how many pixels are printed per inch. Less pixels in the source image == less physical size. David ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Lots of people smarter than myself have worked on Gimp, and I should imagine that my situation is not unique.
