Free Twitter (X) Carousel Maker
1. Add your image
Drop it, paste it, or pick a file. It never leaves your browser.
Works best with a wide image: a landscape screenshot, a panorama, or a design already laid out left to right. The wider it is, the more room each slide gets.
Preview on X
Exactly what you will download.
Testing carousel for X
Upload the slides to X in order: slide-1 first, then 2, 3, 4.

Frequently asked questions

- What is a carousel on X (Twitter)?
- A carousel is simply a post with more than one image. X displays them side by side and lets readers swipe through them. Cut your slides from a single picture and the swipe reveals one continuous image, which is what makes people keep swiping.
- How many images can I put in one X post?
- Four. That is why this tool stops at four slides: exporting more would give you files you could not attach to a single post.
- How do I make a seamless carousel on X?
- Upload one wide image, pick the number of slides, frame it with the zoom and position sliders, then download the ZIP and attach slide-1 through slide-4 to your post in that order. The tool cuts every slide from one composition so the edges match to the pixel.
- Can I use this as a free image splitter?
- Yes. Ignore the X preview and it is a plain image splitter: give it one image, get back 2, 3 or 4 equal numbered pieces in a ZIP. No watermark, no account, no upload limit beyond the 15 MB your browser has to decode.
- What size should my X carousel slides be?
- Portrait slides take up the most room in the timeline. The 3:4 default exports at 1200 × 1600 pixels per slide, which is sharper than X displays and looks clean on high-density screens. Use 4:5 to go taller, 1:1 for square sources, and 16:9 for wide screenshots you do not want to crop.
- Why do the seams not line up perfectly once posted?
- X rounds the corners of each image and puts a small gap between them, so a few pixels at every boundary are never shown. Nothing is wrong with your export. Turn on cut lines to see where the boundaries fall and move important content away from them.
- Does my image get uploaded to a server?
- No. The cutting happens in your browser with the canvas API. Your image never leaves your device, which is also why the tool keeps working if you go offline after loading the page.
- Should I export PNG or JPEG?
- PNG for UI screenshots, charts and anything with text, because it stays razor sharp. JPEG for photographs, where PNG produces files large enough to hit the 5 MB per image limit on X. The tool warns you if a slide comes out too heavy.
- In what order do I upload the slides?
- Slide-1 first, then 2, 3 and 4. The files are numbered for exactly this reason. X keeps the order you attach them in, and a carousel assembled out of order loses the continuity.
- Does it work for Instagram or LinkedIn carousels?
- Yes. The exported slides are ordinary images, so they work anywhere multiple images are accepted. Instagram panorama carousels usually use 4:5, and LinkedIn accepts the slides once assembled into a PDF.
- Is the Twitter carousel maker really free?
- Completely free, with no signup, no watermark and no export limit. It is one of the free tools we build for makers at Uneed.
- Does it work on a phone?
- Yes. Pick an image from your camera roll, use the sliders to frame it, and download the ZIP. Dragging the preview to reposition is a desktop-only shortcut, but the position sliders do the same job on any device.
How to post a carousel on X
X shows a post with several images as a swipeable carousel. That is the whole mechanic behind the posts you have seen where the picture seems to keep going as you swipe: it is not one wide photo, it is two to four separate images that were cut from the same source and uploaded in order. Drop your image above, choose how many slides you want, and the tool does the cutting.
Once you have the ZIP, open X, start a new post, attach slide-1 through slide-4 in that order, and publish. Order matters: X keeps the order you attach the files in, and a carousel assembled out of order reads as four unrelated crops.
What makes a carousel seamless
A seamless carousel, sometimes called a panorama carousel, is one where the slides are cut from a single composition instead of being designed one by one. The reader swipes and the content continues, which is what makes people swipe to the end instead of stopping at the first image.
The tricky part is the cutting. Slice each piece separately, in a screenshot tool or by hand, and the edges drift by a pixel or two and the illusion collapses. This tool composes your image onto a single canvas the exact width of all your slides put together, then cuts that canvas. Every slide comes out at identical dimensions and the seams line up to the pixel.
Use it as a free image splitter
Underneath the X framing, this is a plain image splitter: you give it one picture, you get back the same picture cut into equal numbered pieces. Split an image in two, in three, or in four, at whatever shape you need. Nothing is uploaded, there is no account, and there is no watermark on the output.
That makes it useful well beyond X. Cut a wide banner into square tiles, break a long design into uploadable chunks, or prepare a picture for any platform that wants several images instead of one big one.
The best slide size for an X carousel
Portrait slides win. X gives vertical images far more height in the timeline than landscape ones, so a 3:4 slide occupies noticeably more screen than a 16:9 slide of the same width. 3:4 is the default here for that reason, exported at 1200 × 1600 pixels, which is comfortably above what X displays and leaves room on high-density screens.
4:5 is the taller option if you want to dominate even more of the feed. 1:1 is the safe choice when your image is roughly square to begin with. 16:9 exists for wide screenshots where cropping to portrait would throw away the content that matters.
Why the seams never line up perfectly on X
X rounds the corners of each image in a carousel and leaves a small gap between them. A handful of pixels at every boundary are therefore never visible, no matter how precisely the image was cut. This is a property of how X renders carousels, not a flaw in the export.
The practical consequence: keep anything that must stay readable away from the cuts. Turn on cut lines in the tool to see exactly where the boundaries land on your image, then use the position sliders to nudge faces, logos and text into the middle of a slide rather than across a seam.
Instagram and LinkedIn panorama carousels
The same output works anywhere a platform accepts multiple images per post. Instagram panorama carousels are usually built at 4:5 and accept up to ten images; LinkedIn carousels want a PDF, but the slides exported here drop straight into one. The only setting that changes is the shape, and the slide count ceiling of four here is X's limit, not a technical one.
