Inside Terminal copy and paste this: find NEW -name \*.tif -exec sh -c 'new="$ \ If the TIF files are in multiple directories, you will need to work a bit harder. If all the TIFs are in a single directory or two, just use mogrify: mogrify -format jpg *.tif Then start the Terminal and change directory to "NEW": cd NEW So, let's say you copy (NOT move) the entire tree of TIFs to a subdirectory called "NEW" inside your HOME directory. I would suggest you try the following using ImageMagick.įirst, use the Finder, or any other tool you are familiar with, to make a copy of your photos including the entire directory structure to some new place where we cannot damage your existing photos. You should also be able to extract macOS/Spotlight/Finder comments using the script in my main answer: $HOME/macOSGetFinderComment "/Users/someone/soneFile.tif" You can also extract the EXIF user comments to a CSV with: exiftool -EXIF:UserComment -csv *.jpg Likewise, you can set the comments with: exiftool -comment="FUNKY JPEG COMMENT" image.jpg # set JPEG commentĮxiftool -EXIF:UserComment="FUNKY EXIF USER COMMENT" image.jpg # set EXIF UserComment If you find your comments in the JPEG or the EXIF section, you can extract just the comments with: exiftool -comment image.jpg # extract JPEG commentĮxiftool -EXIF:UserComment image.jpg # extract EXIF UserCommentĪdd the option -s3 to suppress the field-names in the above to save having to parse them out. EXIF:UserComment - which is the EXIF comment.comment - which is the JPEG comment, or.

Then I suggest you try extracting the comments from your files to see how/where they are stored: exiftool -a image.jpg
#HOW TO CONVERT TIFF TO JPG MAC INSTALL#
I recommend using exiftool which you can install with homebrew, using: brew install exiftool
#HOW TO CONVERT TIFF TO JPG MAC WINDOWS#
MacOS Finder/Spotlight comments will not be legible on Windows, so if you want Windows compatibility, you need to standardise on JPEG or EXIF comments. In the light of your comments, I think the best way forward is to try and identify how/where the comments are stored for each platform (Windows vs macOS) and then to decide which method you want to use going forward.
