What os are you using and what pp software. If you are using macos you can actually batch process some changes using preview of all things!
Select all the images in a folder, then right click and select open with preview, once preview has loaded select all the images with [cmd] and A then any changes you make affect all the images so change image size to 1024x798 and then click SAVE ALL under file. Job done
Under windows we would need extra software but it's still quite simple.
