• why though? The graphics represented in the screen are already squashed and scaled, so you wouldn’t be preserving their quality in any case. If you’re worried about text, JPEG should still be able to handle it under high quality settings

      • But that’s patently untrue: take this 10 MB example TIFF file as an example.

        • PNG Compression, max compress (=quality 9):

          convert file_example_TIFF_10MB.tiff -quality 9 test.png
          
        • JPG Encoding, 99% quality (=quality 99):

          convert file_example_TIFF_10MB.tiff -quality 99 test.jpg
          

        Final file size comparison:

        9.7M Sep  5 13:21 file_example_TIFF_10MB.tiff
        1.7M Sep  5 13:22 test.jpg
        2.5M Sep  5 13:22 test.png
        

        PNG is significantly larger, and difference in quality between them is negligible
