Copy icc profile from one image file to another

[hauke]

In my workflow I convert tiff files to png using sips (on Mac):

Code Select Expand

sips -s format png -o myfile.png myfile.tiff(Actually I use an AppleScript with Image Events, but that seems to very much the same.)

Unfortunately Adobe products (and exiftool) don't seem to recognise the icc profile of the new png file. So I thought of copying the icc profile from the tiff to the png file, but couldn't figure out how. When I extract the profile using

Code Select Expand

exiftool -icc_profile -b -wI don't know the name of the resulting profile file. I could probably figure that out from the image file name, but it would be much more convenient to copy it directly from one image file to the other. Is that possible?

Try
exiftool -TagsFromFile myfile.tiff -icc_profile myfile.png

Or in batch, assiming the tiff and pngs are in the same directory
exiftool -ext png -TagsFromFile %d%f.tiff -icc_profile /path/to/files/
