Carousel splitter: one image into perfect slides
Slice a wide or panoramic image into carousel slides at the exact size Instagram expects. Free, in your browser, no watermark.
A seamless (panoramic) carousel is one image that continues across slides — the design trick with the strongest scroll-stopping effect on Instagram. The catch: Instagram only accepts individual slides, so the wide image has to be cut into exact 1080-pixel-wide pieces, all at identical dimensions. That precision is what this tool automates.
Design your strip, split it here, and upload the numbered slices in order. For the full technique — canvas math, design rules across seams, and the pitfalls that break the illusion — read the seamless carousel guide. If you just need the right dimensions for a regular carousel, they are in the Instagram carousel size guide.
How do I split an image into an Instagram carousel?
Drop the image into the splitter above, pick the slide ratio (4:5 portrait or 1:1 square) and the number of slides, and click Split. You get numbered PNG slices at exactly 1080×1350 or 1080×1080 — upload them to Instagram in order and the image flows across the carousel.
What image size works best for a seamless carousel?
Design one wide canvas at N×1080 pixels wide and 1350 pixels tall, where N is the number of slides. A 3-slide seamless carousel is 3240×1350. The splitter also center-crops other sizes to fit, but designing at the exact strip size gives you full control of what lands on each slide.
Does the splitter upload my image anywhere?
No. The splitting happens entirely in your browser with the canvas API — the image never leaves your device, and there is no watermark on the output.
Why do my slices look misaligned when posted?
Every slide must share identical dimensions, which the splitter guarantees. Misalignment usually comes from uploading slides out of order, or letting Instagram apply the Mixed ratio option — keep all slides at one ratio for a seamless flow.
