Title: removing exif data so it can't show up even in exiftool
Post by: nnoidone on June 25, 2010, 07:28:49 PM
Hi,

I use GraphicConverter for Mac to view and edit my pictures. I would like to send/post some of these pictures online but do not want to include all the exif information that shows up when I click on the "EXIFTOOLS" box in the "Information" window that GraphicConverter displays with each picture.

I was able to delete the exif information using the Cocoviewer freeware app, but when I then open the picture in GraphicConverter, all the private information I wanted to delete from the exif file still shows up in the "EXIFTOOL" information box. :(

How can I remove ALL the exif information so that NONE shows up, even in EXIFTOOL?

Thanks!!! :)

The following command will do what you want:

exiftool -all= FILE

I think I figured it out...what I'm seeing in the "EXIFTOOLS" window in GraphicConverter is only the information about the location, date, etc. of that particular picture at that time...since the EXIF window is blank, I think that means that if it's sent to someone else, they will only see the EXIFTOOLS info for the picture on their computer (assuming they HAVE EXIFTOOLS ;) lol)

Let me know if that's correct...and, if not, what I'm missing :)

Thanks!  :D

GraphicConverter displays the result of the following command:

exiftool -a -g1 FILE

which will show the following basic information about a JPEG image even if it contains no metadata:
