Fitting a rectangular image into a square canvas

Edit > Content Aware Scale  — using the Protect feature.  That means roughly selecting the three people and saving the selection. When you use CAS click on Protect, and load the selection you made of thge people.  Works a treat.

There are multiple solutions for this problem. It depends on the content of the actual image; perhaps you can simply crop it, or maybe it's easy to fill the additional space, or it could be difficult if people are very close to the image edges. Can you provide a sample image for the best recommendation?

It depends on the image content if the following is viable:

The only way to make a rectangle into a square without distorting the people in the image is to crop it. There is no other way. Select the crop tool. In the crop menu bar, choose "square". Crop. 

When fitting a rectangular image into a square frame you have only three choices:

1. Crop the rectangle to the square.

2. Distort the rectangle to the square.

3. Fit the rectangle inside the square and then fill the blank areas using solid colour, another image, or content aware/generative fill.

Which is the best solution depends on the image.
