Filter JPGs by megapixel size

[and78386]

Hi all,

Windows 10 user with IrfanView 4.6 here. I have a big folder with many JPGs in it.

I want to move all JPGs with a megapixel size smaller than 12 megapixel to a separate folder.

How can you do that?

Cheers,
Andreas

You can almost do it in Windows Explorer. Show file details, enable the column for dimension (in pixels), and sort the file list by dimensions.
3000x4000 = 12 Megapixels, but there may be some images with different aspect ratios that are less than 12 Megapixels. I did not find any option to show a column with Megapixel sizes.

The task can be solved with this command:

exiftool -directory=DESTDIR -if "$megapixels < 12" -ext jpg SOURCEDIR
