Carousel splitter

Cut one wide image into seamless Instagram carousel slides that flow into each other as people swipe. Free, and your image never leaves your device.

Your image stays on your device. Nothing is uploaded.

How it works

  1. 1

    Choose a wide image

    A panorama, a banner, or a design you made wide on purpose so it flows across the slides.

  2. 2

    Pick slides and shape

    2 to 10 slides, portrait 4:5 (1080 × 1350) or square (1080 × 1080). Slide the crop until it sits right.

  3. 3

    Download and post

    Save the numbered slides, or all of them as a ZIP, and post them in order as one carousel.

Questions

What size should a seamless carousel image be?

Slide width × number of slides, by the slide height. For portrait 4:5 slides that's 1080 × 1350 each, so 3 slides need 3240 × 1350 and 5 need 5400 × 1350. A smaller image still works; the tool tells you when slides will look soft.

Is my image uploaded anywhere?

No. The image is cut on your own device, in the browser. Nothing is sent to PostStage or anyone else.

Will the slides line up when people swipe?

Yes. Each slide starts at the exact pixel where the one before it ends, so the picture continues across the swipe with no gap or overlap.

Portrait or square?

Portrait 4:5 takes up more of the screen in the feed, so it's usually the better choice. All slides in one carousel use the same shape.

How do I post the slides as a carousel?

Add them in order (they're numbered 01, 02, 03…) to a new Instagram post. With PostStage you can schedule the carousel to go out at an exact time, from your computer.
