What a split carousel actually is
A split carousel is one picture cut into vertical panels and posted as a single carousel post. As the
reader swipes, the panels line up and the whole thing reads as one continuous image scrolling sideways.
It works because carousel slides sit edge to edge in the viewer, so a cut that lands in the right place
disappears.
That is a different job from a grid mural, which is one image cut into square tiles and posted as
separate posts so the profile grid assembles into a picture. If that is what you are after, the
Instagram grid maker does that one, and the posting order for it is
counter-intuitive enough that it needs its own page.
Getting the cuts right
Two things decide whether a split carousel works.
Pick the slide shape before you pick the picture. A 4:5 slide is much taller than it is wide, so
four of them side by side need a source image roughly three times wider than it is tall. If your source
is not that wide, the tool crops from the centre to make it fit, and you lose the left and right edges.
Starting from a genuinely wide image is the difference between a panorama and a centre crop.
Keep anything important away from the seams. A face or a word that lands on a cut is split across
two swipes and reads as a mistake rather than an effect. Use the preview strip above, pull the slides
apart, and check what each one contains on its own — every slide has to survive being looked at
individually, because plenty of people will only see the first one.
What you get
A ZIP containing one PNG per slide, named slide-01.png upwards in swipe order. Upload them in that
order and the panorama reads left to right. All of them are the same pixel size, none of them are
watermarked, and no part of the process touches a server.
Frequently asked questions
- What size should each slide be?
- For an Instagram feed carousel, 4:5 portrait takes up the most room in the feed and 1:1 square is the safe alternative. For TikTok, Stories or Reels-style vertical sets, use 9:16. Whichever you pick, every slide in the set has to match, which is why this tool renders them all at one size.
- How many slides should I split into?
- Between three and six usually holds together. A panorama stops reading as one continuous picture once there are too many cuts, and each extra slide is another swipe you are asking someone to make. Instagram allows up to 20 slides in a carousel, but that is a ceiling, not a target.
- Does the image get uploaded anywhere?
- No. The file is decoded, cut and packaged into a ZIP entirely by your browser using canvas. There is no upload step, no server call and nothing stored, which also means the tool works with the tab offline once the page has loaded.
- Why do the slides look slightly different widths in the preview?
- They do not — they are all rendered at exactly the same size. What varies by up to a single pixel is the region each one is cut from, because most image widths do not divide evenly by the number of slides. Rounding the cut points rather than the slide widths is what keeps the seams gap-free.
- Is there a watermark?
- No. The PNGs this tool produces carry no watermark and no branding of any kind.
- Can I post the slides straight to TikTok or Instagram?
- Not from this page. You get a ZIP of PNGs, and you upload them yourself in the order they are numbered. Both apps let you pick several images at once when you create a carousel post.
