photo editing – image to 1:1 cube faces or 2:1 spheres


When uploading jpeg to Marzipano.net tool, the error returns with “Images not 1:1 cube faces or 2:1 spheres”

After googling for an online converter and using a few, the error is still the same.

Also downloaded and tried using Microsoft Image composite editor (still have it on my computer).

I just do not know how to make an image to 1:1 cube faces or 2:1 spheres.
