What's the best way to deal with the issue of an image being too long in the vertical dimension to fit without cropping? Is there something that can be done natively to IG? I've seen people recommend apps, is there anything that can be installed on a desktop PC, rather than going on my phone?
I always use Photoshop to make a square frame ( 1080*1080 px) , specially when i want to design a typography pic for my Instagram page ... if you can't access to Photoshop ... I recommend you a useful app "Inshot" Inshot helps you to make square photo, put watermark on pic and videos and convert video to be upload on instagram https://play.google.com/store/apps/details?id=com.camerasideas.instashot&hl=en_GB
