Post-processing: Removing embedded thumbnail images

Check for embedded thumbnail images:

magick identify {filename}

or

identify {filename}

If a thumbnail is embedded, the output will list more than one ‘page’, one of them with a lower resolution. Double-check which of the images is the thumbnail (usually the second).

Remove thumbnail image:

exiftool -ifd1:all= -m {filename}

This command will remove the second and all subsequent pages. The tool will create a backup of the original image.
