Why pre-sizing beats in-app cropping
Upload an odd-sized photo and Instagram decides what gets cut — often the edge of a face or the product you were showcasing. Sizing to 1080×1080 first means you control the frame and see the final composition before it goes live.
Quality survives upload
Instagram recompresses everything, and oversized images get hit hardest. Uploading at the native 1080px width gives the algorithm the least to mangle — your photo arrives looking like your photo.
Other Instagram formats
Portrait posts (1080×1350) show larger in feed; stories run 1080×1920. For a portrait or story-format image, use Resize Image with those exact dimensions. Files are processed temporarily and deleted automatically — there is no general cloud storage.
