jpegtran didn’t do “copy none”.
It’s the only time I have come across this.
A jpg file with metadata that didn’t clear with jpegtran.
I use it like this…
~ $ jpegtran -V mozjpeg version 4.0.4 (build 20210706)
~ $ jpegtran -copy none -outfile new_filename.jpg filename.jpg
I have put the results in the attached results.txt file because they are verbose,
It didn’t get rid of the icc profile, looks like the only difference is timestamps.
But I could delete it using Exiftool.
It’s not such a big deal.
Exiftool shows all the metadata…
exiftool -a -u -g1 filename.jpg
Delete icc profile…
exiftool -ICC_Profile= filename.jpg
Delete all metadata…
exiftool -all= filename.jpg
