Instagram Image Resizer

Portrait at 1080x1350, the 4:5 ratio. It occupies noticeably more vertical space than a square post, which means more time under a scrolling thumb. The tool's Post Portrait preset outputs exactly that.

When your upload doesn't match a supported ratio, the app forces a crop at posting time with a clumsy pinch interface. Resizing to 1:1, 4:5, or 1.91:1 beforehand removes the guesswork, because the file already fits.

Yes, both use the 1080x1920 preset at 9:16. Keep in mind Instagram overlays your username at the top and interaction buttons at the bottom of Stories, so leave breathing room at both edges.

Scaling down from a larger original preserves sharpness well; the tool exports at 92 percent quality in your image's original format. Scaling up a small image can't add detail, so always start from the largest file you have.

Cover suits photos where the subject sits near the center, since it fills the frame edge to edge. Contain suits artwork, screenshots, or products that must stay complete, at the cost of white bars.

Yes, 1080 is the width Instagram itself serves. Upload wider and the platform downscales it for you, sometimes with visible softening. Delivering the native 1080 width means your own resize, not Instagram's, decides the final look.

The uploader accepts images up to 20 MB, which covers raw exports from any phone and most cameras. Processing happens on a canvas in your browser, so the photo never leaves your machine.
