So many of my clients use photos only on a social media/online presence. I would like to offer digital downloads with options to crop according to the aspect they need.

For example: My original photos may be cropped at 2x3.

But facebook and instagram prefer 4x5.

I would like to give them the option to download those files and they can crop accordingly to that aspect ratio at 2048px (the standard for social media).

Same with a square 1x1 crop or if they need it as a facebook banner at 16x9.

Then they could download the same image but with multiple sizes to be used for all their social media outlets.
