Batch Resize Transparent Background PNG's Using Long Edge

Question

I had about 200 images that are very large high res PNG files with transparent backgrounds. Some are vertical and some horizontal. I needed to resize all of them so they are 800 pixels on the long side @14451451, saved as a PNG with a transparent background (just like they currently are).

I spent about 2 hours searching how to batch resize in Photoshop like I can in LR using the long edge, but could never find a way to do this using actions or scripts (scripts>Image Processor only does jpegs, psd, or tiff, not png's, not sure if you can preserve transparency). I'd love to hear how to do this if anyone happens to know.

Why isn't there an option to just select the long edge when resizing and set it the way you want like you can in LR?

I ended up doing it manually which really sucked. Any help would be appreciated!

I'm running Photoshop CC 20.0.2 on a new Mac Pro running OS 10.14.1, 64GB ram, 1TB hard drive.

Thanks in advance for your help,

Ken
