Hello
I am sure that not the first time, but I find not my response

when I use ImageMagick  there is an option -quality and I put 70 and I see it with Xnview estimated quality


How with ImageInfo I can retreive this information ?

Thank for your help

Serge

Hi Serge,

See the JPEGQualityEstimate tag in the ExifTool Extra Tags documentation.

...where DIR is the name of a directory/folder containing the images.  On Mac/Linux/PowerShell, use single quotes (') instead of double quotes (") around arguments containing a dollar sign ($).
