I would like to change the format of a screenshot from .png to .tiff. Is this possible? Moreover, is it possible to write a script or some equivalent that can automate screenshots on any apple mobile device i.e. iPhone and/or iPad?

    png is lossless anyway, so why would you really need tif? – Tetsujin Jul 22 '15 at 20:01
  • I don't want any compression on the files for archival and editing purposes. png format also supports lossy compression as well I take it? Am I simply to take Apple in full faith that they use lossless compression? – Quesop Jul 22 '15 at 20:47

It is currently not possible to change the format of screenshots from PNG, however there are many ways to change image using a PC.

As for your second question, this is only possible by jailbreaking your iOS device and installing SSCapture.

  • Do you know of some convenient clever workaround I can use to change the default format, perhaps via jailbreaking one of my older devices with expired warranty? – Quesop Jul 22 '15 at 20:50
  • You could try and install ImageMagick to help you convert the png into a tiff file. – user137325 Jul 25 '15 at 6:19
