Frequently asked questions
Is 1080×1080 the best Instagram size?
It is the recommended square post size, balancing sharpness and file size on the feed.
What if my image isn’t square?
It is fitted centrally to the square so it is not stretched; drag to reposition using the square cropper if you prefer a specific crop.
Is my photo uploaded?
No, it is resized locally in your browser.
