Split an image into carousel slides

FreeNo uploadNo signupWorks offline

A seamless carousel is one wide picture cut into equal pieces that line up as you swipe. Design the whole thing on one canvas, drop it here, and choose how many slides – the pieces come back numbered in posting order, as a ZIP. The cutting happens on your device, so an unpublished design is not uploaded anywhere to be sliced.

The canvas size for each number of slides

A seamless carousel is one wide picture cut into equal pieces, so the canvas is simply the slide width multiplied by the number of slides. At the 1080 px width every common slide shape uses, that gives the figures below. Design at the full width, then cut – designing each slide separately is what produces the visible jumps at the joins.

Canvas width for a 1080 px slide
Slides	Canvas (portrait 4:5)	Canvas (square 1:1)
2	2,160 × 1350 px	2,160 × 1080 px
3	3,240 × 1350 px	3,240 × 1080 px
4	4,320 × 1350 px	4,320 × 1080 px
5	5,400 × 1350 px	5,400 × 1080 px
6	6,480 × 1350 px	6,480 × 1080 px
7	7,560 × 1350 px	7,560 × 1080 px
8	8,640 × 1350 px	8,640 × 1080 px
9	9,720 × 1350 px	9,720 × 1080 px
10	10,800 × 1350 px	10,800 × 1080 px

Nothing is lost at the joins

If the width does not divide exactly by the number of slides, the cut points are rounded so the pieces differ by a pixel and the full width is kept. The obvious alternative – dividing, rounding down, and cutting that many equal pieces – quietly discards a column off the right-hand edge, which on a seamless design shows up as a jump at the last join. The result says when this happened.

About "the correct Instagram size"

Guides disagree: some say 1080 × 1350 (4:5), others 1080 × 1440 (3:4), and the argument is why most people end up searching for this. We went looking for a figure published by Meta and did not find one worth citing – the most official-looking page is an AI summary sitting above a thread of user posts, one of which contradicts it. So this page does not assert a current official size. What is certain is the arithmetic: whatever slide shape you design for, the canvas is that width times the number of slides, and all three common shapes are 1080 px wide. Pick the shape you want, and the tool cuts to it.

Posting them in the right order

The files are numbered 01, 02, 03 and so on, left to right. Upload them in that order: most phone galleries sort by name, so selecting all of them usually gets it right, but a gallery sorted by date taken can reverse them. Check the first slide is the left-hand edge of your design before you post – that is the one mistake this tool cannot catch for you.

Limitations

Up to 10 slides.
Cutting only – the slides are not resized, so design at the size you want to post.
Animated files are reduced to their first frame.

Privacy

Files you choose are read into your browser’s memory and processed on your device; they are not uploaded to a server. Temporary download links are released after use, and the offline cache never stores your documents. More about privacy and limits.

Frequently asked questions

How wide should my canvas be?

The slide width times the number of slides. Every common slide shape is 1080 px wide, so six slides means a 6480 px canvas – the table above has the rest.

How many slides can I have?

Up to 10 here. Instagram allows more in a post, but a seamless design past ten slides is very wide and very heavy to edit.

What is the correct size for an Instagram carousel?

Guides disagree, and we could not find a figure published by Meta worth citing. All the common shapes are 1080 px wide and differ in height – 1350 (4:5), 1080 (1:1) or 1440 (3:4). Choose the shape you designed for; the arithmetic for the canvas is the same either way.

Will the slides line up exactly?

Yes. The cuts are made from the exact fractions of the width, so the pieces reassemble into the original with no column missing and no overlap.

Can I split for a profile grid instead?

Yes – the grid splitter cuts into rows and columns rather than a single strip, and tells you the reverse order a grid has to be posted in.

Is my image uploaded?

No. It is cut up inside your browser and the pieces are saved to your device. Nothing is sent to a server.

Is it free?

Yes – free, no signup, no watermark, and the pieces come without anything stamped on them.
