How to remove EXIF data without recompressing the JPEG?

by

exiftool does the job for me, it’s written in perl so should work for you on any o/s

https://exiftool.org/

usage :

exiftool -all= image.jpg

UPDATED – as PeterCo explains below this will remove ALL of the tags. if you just want to remove the EXIF tags then you should use

exiftool -EXIF= image.jpg
