Compare side by side JPEG export between original reduced quality

Is there a way to do a side by side compare of JPEG exports between original and reduced size? Photoshop has this feature when exporting an image for web.

No.

There has been repeated request for export preview and devs know it is needed. (I prefer before/after comparison.)
