Cut a wide photo into slides that run edge to edge when someone swipes.
A panorama split across carousel slides reads as one continuous picture as the reader swipes. The cut has to be exact or the seams show, so the crop is applied once across the whole image and then divided, in your browser.

Splits one wide image into carousel slides at Instagram’s 1080 px width. Works best on a genuine panorama: the wider the source, the less gets cropped away vertically.
A seamless carousel is convincing only if the slides join perfectly. A single pixel of overlap or gap is visible the moment someone swipes, because the eye is tracking a continuous line across the join.
This is why the crop runs once across the whole image and the result is divided, rather than each slide being cropped independently. Independent crops accumulate rounding error, and the error lands exactly where it is most visible.
Three portrait slides at 4:5 need a source roughly 2.4 times as wide as it is tall. Six slides need about 4.8:1, which is a genuine panorama rather than a wide photo.
Feed it something narrower and it still works, but the top and bottom are cropped hard to reach the required shape, and you lose most of the picture. The tool measures your image against what the chosen slide count needs and says so before you export.
Instagram allows up to ten images in a carousel, so ten is the maximum here. In practice fewer is usually better: every extra slide demands another swipe, and completion falls off quickly after about five.
For the individual slides, portrait 4:5 takes more vertical space in the feed than square and generally earns more attention, at the cost of needing a wider source to fill.
