DPI
Prepare photos for a print shop: choose up to three print sizes, check each crop and pixel shortfall, then export verified files with a delivery report. Reuse named print setups and create a test-print PDF with a 100 mm ruler. You can also change the DPI tag for up to 50 photos at once. JPEG, PNG and HEIC, all on your iPhone with no upload and no account.
The DPI tag changes without re-encoding your photo. After export, DPI, pixel size and file size are read back from the new file.
