How can I convert CRW format images to JPG or PNG via terminal. tried convert and mogrify with no luck. It gave a weird corrupted error while processing the CRW files but I can view them fine using Shotwell for example.

Imagemagick, according to http://www.imagemagick.org/script/formats.php, supports CRW (Canon Raw Image Format), which as such should work with convert.

$ convert source.crw target.jpg

If this does not work there are two options:

  1. Your source image is corrupted
  2. Imagemagicks support of crw is flawed,

in which case you should report a bug at http://www.imagemagick.org/discourse-server/.

  • you are correct. It is flawed. I will report the bug thanks. – Luis Alvarado May 12 '12 at 22:54

I believe "ufraw" should allow you to convert them with a GUI or via command line with the ufraw-batch command.
