Exporting square-fit photos for website
I need to edit my product photos (some portrait, some landscape orientation), and then export them all to fit in a square box for my website without cropping.
On my phone, I use an app called Squarefit to do the same thing but for instagram etc. Is there a way to do this easily in Lightroom? If I could set it up to export all photos this way (and orient them properly in the square automatically) it would be a dream. It's a level 5 pain in the ass to have to transfer photos to my phone to use Squarefit, then back to my computer to upload to the website haha. Thanks in advance for any help.
Here is an example of this I found on the internet. Notice the white bars on the top and bottom that make it a square; this is what I'm looking for.
