Export tif image with 300 ppi - Roberto Pinto - 12-22-2024 When I export a 300 ppi image to tif, Gimp generates a file with 72ppi only and not 300 ppi as desired.

Open an image, jpeg or maybe RAW change resolution to 300 ppi and an exported tiff keeps the dpi. I do turn off layers.. most of the other tick boxes but keep exif data.
