FAQs
How do I make a seamless Instagram carousel?
Start from one wide image, split it into equal slides, then upload those slides in order as a single carousel post. When someone swipes, the pieces line up and read as one continuous picture. This tool does the splitting at exact pixel boundaries, so there is no visible seam where two slides meet.
What size should each carousel slide be?
1080x1350 for a portrait carousel, which is the 4:5 shape that occupies the most room in the feed. Square slides are 1080x1080. Every slide in one carousel has to be the same shape, because Instagram applies the aspect ratio of the first image to all of them and crops the rest to match.
How wide does my original image need to be?
At least 1080 pixels multiplied by the number of slides. A three-slide portrait carousel wants a source at least 3240 pixels wide, and five slides wants 5400. Anything narrower gets enlarged to fit, which softens the result. The tool tells you when your source is below the mark.
Why do my slides look blurry after uploading?
Instagram recompresses everything on upload, and it is harsher on images it has to resize first. Exporting at exactly 1080 wide per slide avoids that second resize. Uploading from the phone app rather than the desktop web version also tends to preserve more detail.
How many slides can a carousel have?
Instagram allows up to 20 in a single carousel, though this tool caps the split at 10 because a panorama stretched further than that stops reading as one image. Three to five is the sweet spot for a wide photo.
Do I upload the slides in a particular order?
Yes, left to right, and the files are numbered 01, 02, 03 to make that straightforward. Most phone galleries sort by filename, so selecting them all at once usually keeps the right order. Check the sequence in the Instagram preview before posting, because a swapped pair is obvious once the panorama is live.
Will the seams line up exactly?
Yes. The full panorama is rendered once at the combined size, then cut at exact integer pixel boundaries, so the last column of one slide and the first column of the next are genuine neighbours from the same render. There is no overlap, gap or rounding drift.
Can I see where the cuts will fall before I export?
Yes, turn on the slice guides and the preview draws a line at every seam. It is worth checking, because a cut landing on a face or a word is the one thing that breaks the illusion. Drag the image or adjust the zoom until the seams sit somewhere forgiving.
Are my images uploaded anywhere?
No. The splitting happens in your browser on a canvas element and nothing is transmitted. Your image never leaves the device.
What format should I export?
PNG if the image contains text, flat colour or graphics, because Instagram's recompression is unkind to those. JPG at quality 90 or higher is fine for photographs and produces much smaller files.
