Which cmd command can delete all metadata info from jpg image?

[Jenis]

I'm looking for a cmd command which can clear all image metadata.


I tried this command:

Code Select Expand

exiftool -exif:all= img.jpg
But it didn't work. All info is still on its place. Also I'd like to forbid exiftool to create a duplicate of original file.

-EXIF:All= will only delete metadata from the EXIF block and won't touch the many other types of metadata.  Try using -All= instead.  Take note that there are several file system related info (usually Date/Time stamps) and image related (such as image dimensions) that cannot be removed and will stil show up in the Windows Properties dialog.

To avoid creating backup files, add the Overwrite_Original option.

Thank you!

Will exiftool fix warnings and errors with this command?

Can you tell me the right line to fill in this Description?

I tried this:

Code Select Expand

exiftool -All= -overwrite_original -m -q -q -ImageDescription="Title" -XPTitle="Title" -XPComment="Comment" -XPKeywords="Keywords" -XPSubject="Theme" -Title="Title" -Description="Title" -Subject="Keywords" -Rating="5" -RatingPercent="99" -LastKeywordXMP="Keywords" img.jpg
And it works:

Code Select Expand

but it adds some info like "Y Cb Cr Positioning : Centered". I don't know is it right or wrong.

Take a look at this post which lists what tags Windows reads to fill the Properties window.

Thank you, I read it. But I'm still not sure do I have to change my line that I wrote above or not?
