Instagram carousel and panorama splitter
The short answer
This splitter cuts one wide image into 2–10 slides at 1080 × 1080 or 1080 × 1350 each, numbered in swipe order, and packages them as a ZIP — checked 29 October 2026.
Source: Instagram Help — photo resolution · Last checked · CORROBORATED
Instagram’s Help Center says photos are shared at up to 1080 px wide, and Meta’s developer documentation accepts feed images from 4:5 to 1.91:1, so 1080 × 1080 is the full-resolution square. Instagram moved the profile grid from squares to 3:4 tiles in January 2025 without publishing a tile size; the centred 3:4 crop shown here is the default before you adjust the grid preview.
Splitter workbench
Add one wide image
A panorama or any wide graphic. The wider it is, the more slides it supports without upscaling.
Nothing is uploaded. The file is read by this tab only.
Runs on your device. Your image is decoded, cropped and encoded by this browser tab. It is never uploaded, and there is no image-processing service behind this page.
Why this asset is awkward
A panoramic carousel is one image sliced into consecutive slides so that swiping feels like panning across a single photo. The slicing has to be exact: a few pixels of drift and the seam between slide two and slide three becomes visible on every phone.
This page shows the cut lines over your image before you commit, lets you choose the slide ratio and count, and exports a numbered ZIP so the upload order is unambiguous. The whole operation — decode, slice, encode, archive — happens in your browser.
Slices are taken at integer pixel boundaries from the full-resolution source, and each slide shares its edge exactly with its neighbour. That is the detail most splitters get wrong: resizing each slide independently leaves a half-pixel of drift that shows up as a visible line at every seam.
Exact specification
| Asset | Pixels | Ratio | Formats | File limit |
|---|---|---|---|---|
| Instagram post (square) | 1080 × 1080 | 1:1 | png, jpeg | Not published |
| Instagram post (portrait) | 1080 × 1350 | 4:5 | png, jpeg | Not published |
What the overlays mean
The cut lines mark where each slide begins and ends. Content that straddles a line is split across a swipe, which is fine for scenery and bad for faces and words. Move the image or change the slide count until the lines land in quiet areas.
- Profile grid crop (3:4): keep content here, Post 1:1
- Since early 2025 the profile grid shows 3:4 tiles, so a square post loses a strip from each side there. The feed still shows the whole square.
- Profile grid crop (3:4): keep content here, Post 4:5
- The profile grid shows 3:4 tiles, so a 4:5 post loses a thin strip (about 34 px) from each side there. The feed still shows the whole post.
Three things that go wrong
- 01
Never let a face straddle a cut
A face split across two slides reads as a mistake. Scenery, texture and gradients split invisibly.
- 02
Match the source width to the slide count
For four square slides you need a source at least 4320 pixels wide to avoid upscaling. The tool warns you when the maths does not work out.
- 03
Upload in order
Instagram uses the order you add files, not the filenames. The ZIP is numbered 01, 02, 03 for exactly that reason — add them one at a time in sequence.
Questions people actually ask
How do I split a panorama for an Instagram carousel?
Upload the wide image, choose how many slides you want, and check the cut lines. Export the numbered ZIP, then add the slides to a carousel post in order. Each slide comes out at exactly 1080 × 1080 or 1080 × 1350.
How many slides can an Instagram carousel have?
Instagram supports up to 20 in a carousel; this tool splits into up to 10, which is where a panoramic swipe stops being pleasant to look at and starts being a chore.
Why do my carousel slides have visible seams?
Usually because the slices were resized independently or the source was upscaled. This tool slices from the full-resolution source at exact pixel boundaries, so adjacent slides line up. If you see a warning about upscaling, the source is too small for the slide count you chose.
Is this the same as an Instagram grid maker?
No. A grid maker chops an image into tiles for your profile grid. This splits one image into swipeable slides inside a single post. The feed layout planner on this site covers the grid side.
