Resize Image to 1080×1350 (Instagram Portrait)

1080×1350 is Instagram's tallest allowed feed ratio (4:5), and it's the one creators reach for because a portrait post claims noticeably more vertical screen space than a square as someone scrolls — more real estate means more stopping power. Feed a square or a wider photo into a portrait slot and Instagram will crop it for you, usually chopping the top or bottom of your subject; sizing to exactly 1080×1350 first means you decide the crop, not the algorithm. The whole resize runs on your device, so the shot never touches a third-party server.

Good to know

  • Outputs exactly 1080 × 1350 pixels — the maximum-height 4:5 portrait Instagram will show in the feed.
  • A portrait post occupies more of the screen than a 1:1 square, so it tends to hold a scroller's attention longer.
  • "Cover" fit fills the full 4:5 frame and trims the overflow — no white bars top or bottom.
  • No size cap on this preset, so the export keeps full quality for a crisp portrait.
  • Also the right frame for Pinterest-style tall pins and vertical carousel slides.
  • Runs entirely in your browser — nothing is uploaded and no account is needed.

Frequently Asked Questions

Why use 1080×1350 instead of a square for Instagram?
1080×1350 is a 4:5 portrait — the tallest ratio Instagram allows in the feed. Because it fills more vertical space on a phone than a square, it typically gets a longer look as people scroll, which is why many creators default to it for single-image posts.
Is 1080×1350 safe for a carousel where other slides are square?
Instagram locks a carousel to the ratio of its first slide. If you want every slide to be a full 4:5 portrait, size all of them to 1080×1350; if the first is square, later portrait slides will be cropped to square. Keep the ratio consistent across the set.
Will part of my photo get cut off at 1080×1350?
Only the parts that fall outside the 4:5 frame. The tool uses a cover crop that scales your image to fill 1080×1350 and trims the overflow, keeping the natural proportions — so it's worth checking your subject sits within the taller frame before exporting.
Are my images uploaded to a server?
No. The resize happens on a canvas in your browser, so your photo never leaves your device and we never see it.
