Hello,
I know exiftool can extract embedded thumbnails... but can that be chained within exiftool's Swiss-army-knife of tools to extract and scale / reduce thumbnails to an arbitrary size? i.e. say the size of a 128x128 pix jpg?
thx! ;D
ExifTool doesn't do image manipulations. It will only extract the embedded thumbnails in their original size.

Thank you for the fast reply! :-)
So...
- can I pipe the extracted jpeg to another process, say the Mac's built in 'scriptable image processing system' to do scaling etc. or will exiftool only generate the file after which I can do something with it with another command?
- how can I get exiftool to extract the largest preview since sometimes there are more than 1 JPEG previews
1. You can pipe the thumbnail to another application like this:
exiftool -thumnailimage -b FILE | some_other_app
...but the other app must have the ability to read the image from the standard input.
2. The BigImage Composite tag in the example config file (https://github.com/exiftool/exiftool/blob/master/config_files/example.config) gives a way to extract the largest preview image. (Not including the thumbnail.)
