Selectively resizing out of thousands of photos

I'm new to Mac and needed something to resize large numbers of sports photos. It does a good job and is easy to figure out how to make it work..... HOWEVER, since I pick and choose out of thousands of pictures in a folder, if I happen to click in the wrong spot, it looses all my selection unless I am constantly hitting "OPEN."

Makes Quick Work of Resizing

This is just what I needed to quickly and intuitively resize thousands of photos I had processed in Lightroom and exported at full resolution. But then found out I needed them to be smaller for another use.

The photos are organized by topic and date so it would have been a real pain to go back into Lightroom and re-export at the smaller image size.

Yes, I must go through each folder catagory one by one but the Image Size window is easy to use, the conversion sizes are easy to set and file name changed to show the resize as well as output folder is selectable. Just remember to create new folders outside the app before you do your batch resizing.

Not hard to figure out and a massive time saver.

It's ok but slightly annoying

It works as intended, but every time you use it, you have to select an output directory.
It should be smart and offer you by default the same directory where the source images are located.
And when you want to close the app, it shouldn't ask you about whether you really want to close it.
