Bulk Crop Images Plugin Needed

I am looking for a good plugin that will go through about 600 posts and automatically crop all images down to 1024 on the long side. I have a lot of images that were uploaded over the years well over a few MB. WordPress has made smaller versions, but it is too big of an undertaking to go through and clean this up manually. I use Smush.It but many of the images are well over 1MB, and I can never get Smush it to bulk through all the images, it always stops after not too long of running and has to be re-run over and over again. I thought about just downloading the folders and just running it through photoshop or something but was hoping for an easier way.

Any help would be great.
