ImageMagick is probably the best bet, but if you want a GUI try XnConvert
Using BIMP? One factor is BIMP will not remove any Metadata which might amount to 30 or 40 KB of the file size.
For a GUI application I would use XnConvert https://www.xnview.com/en/xnconvert
A few screen shots to get you started
Add as many files as you need, you can see these about the 3 - 3.5 MB file size and tagged as having exif data https://i.imgur.com/0IQIvkj.jpg
Add an action, resize to 800x800 but keep aspect ratio https://i.imgur.com/6xDDGrq.jpg
Then in the output settings - untick all the keep/preserve options quality is going to be about 50, ticking progresive saves a couple of KB and sub-sampling to lowest. https://i.imgur.com/RsGxkyK.jpg
That gets the original 3.7 / 3.2 MB 3000x2300pix files down to 63 / 64 KB 800x600 pix
Not much benefit with jpeg going below 50 quality. If you can not get a small enough file size, you need a smaller final image size.
Quote:I am taking images with a Canon DSLR camera and they come into GIMP at 3MB+ and I want to scale them down to 800 x 800 and 72KB max.
I have tried the Batch GIMP Plug in for scale and that is working for the 800 x 800 but the files end up as different file sizes (between 50-150K).
Is anyone aware of a batch plug in I can use that will produce both 800 x 800 and also file sizes maxed to 72KB?
