I’ve been trying to export photos for a magazine, the magazine wants my photos at 300 dpi. I have no idea nor do I see any options on how to change the file size of my photos on Adobe Lightroom mobile. Does anybody know how I can export my photos in a lower pixel size?
Actually, 300dpi is not a file size, it is a tag that tells page layout software how to place your image on a printed page. Changing the dpi up or down has absolutely zero effect on the pixels and overall size of your image.
Unfortunately, Lightroom Mobile does not have export controls to adjust the dpi setting on the images you export. You would need to bring the images into Photoshop, or Lightroom Classic (or some other software), to be able to export with a different dpi setting.
