There are a few things you can do to post on Instagram without cropping. First, use the “crop” button in the top right corner of your Instagram account’s main screen. This will resize your photo so that it is less cropped and more like a normal image. Second, use the “share” button to share your photo with your followers. Third, use the “edit” button to make changes to your photo and then share again. Finally, use the “delete” button to remove your photo from Instagram.
