iPhone

Set photos to 300 DPI for print. Pixels stay the same — only DPI metadata changes. Change the DPI metadata of your photos for print-ready files. This app does not resize your images. It updates only the DPI metadata stored in JPEG, PNG, and HEIC files. It is not an image upscaler or enhancer. WHO IT'S FOR • Print submissions that require 300 DPI • Research papers and reports with image requirements • Checking print size before photo printing HOW IT WORKS 1. Choose a photo or image file 2.
