Instagram grid maker and carousel splitter

Split a photo for Instagram: puzzle grid or seamless carousel

This Instagram grid maker cuts one photo into 3, 6, 9, 12 or 15 tiles that rebuild the picture on your profile, or into 2 to 10 slides for a seamless panorama carousel. You frame the image by dragging it, see a preview of your profile and of the swipe, then download every tile at the exact size, numbered in the order you need to post them.

Everything happens in your browser: the photo is never uploaded, and there is no account, no watermark and no usage limit. The tool takes into account the 3:4 profile grid introduced in 2025 and warns you when a format will be cropped in the grid.

1. Add your photo

   Click “Choose a photo”, drop a file onto the tool, or paste an image with Ctrl+V (⌘V on a Mac) or the “Paste image” button. JPEG, PNG and WebP work everywhere; HEIC photos from an iPhone open in Safari.

2. Choose the layout

   Select “Profile grid (puzzle)” and the number of “Rows of 3 posts”, or “Carousel (panorama)” and the “Number of slides”. Then pick the “Tile format”: 3:4 for a seamless grid, 4:5 or 3:4 for a carousel.

3. Frame the image

   Drag the photo in the framing area, zoom with the slider (or pinch on a phone) and click “Reset framing” to start over. Tick “Show the whole photo” to fit it without cropping, on a background colour of your choice.

4. Check the preview

   The profile preview shows the tiles as 3:4 thumbnails, the way Instagram displays them, and the “Show 3 older posts” option places them above existing posts, as on a real profile. You can swipe the carousel preview to check every join.

5. Download and post

   Click “Download all (ZIP)”, or a single tile under “Tiles in posting order”. On a phone, “Share or save to Photos” opens the share sheet, where you can save all the images to your gallery, if your browser supports it. Post tile 1 first.

How the Instagram grid split works

The tool builds one large picture made of the tiles side by side (for example 3 × 3 tiles of 1080 × 1440 px, so 3240 × 4320 px), places your photo in it and cuts it with no gap and no overlap, so the edges of neighbouring tiles match to the pixel. Each tile is then rendered on its own at full size, which keeps memory use low, even on a phone.

• Posting order: Instagram puts each new post at the top left of the profile and pushes the others right and down. The bottom-right tile must therefore go up first and the top-left one last; the numbers on the framing and the file names (01 to 09) follow that order.
• Whole rows only: the grid always has 3 columns and you post a multiple of 3 tiles, so the puzzle lands exactly on complete rows, whatever the number of posts already on your profile.
• 3:4 thumbnails: since January 2025, profile thumbnails are 3:4 rectangles. A 3:4 tile shows in full; a 4:5 tile loses about 3.1% of its width on each side and a square tile 12.5%, which breaks the joins. The dotted lines on the framing show what stays visible.
• Carousel: when swiping, the slides are shown in full and edge to edge, so a panorama looks continuous. On your profile, only slide 1 appears, as a 3:4 thumbnail.
• Export: JPEG at 92% quality by default (adjustable from 50 to 100%) or PNG, 1080 px wide; the ZIP stores the files without recompressing them (the images are already compressed) and opens with the Files app on iPhone, on Windows and on macOS.

For sharp tiles, the photo should be at least as large as the “Full picture” shown under the settings. A 12 MP phone photo held upright (3024 × 4032 px) is almost exactly the 3240 × 4320 px of a 3 × 3 grid in 3:4; if the photo has to be enlarged a lot, the tool tells you.

Instagram grid and carousel sizes

What a split grid or carousel is good for

• Launching or rebranding a profile: a large 3 × 3 visual makes a strong impression as soon as someone opens the profile.
• Announcing an event, a product or a collection: a poster split into 3 or 6 posts takes over the top of the profile for the whole campaign.
• Showing a landscape or a group photo: a panorama carousel keeps the full width that a single post would shrink.
• Telling a story slide by slide: a continuous carousel (an illustration, a timeline, a step-by-step tutorial) invites people to swipe to the end.
• Photographers, artists and shops: a row of 3 posts used as a banner between two series keeps the profile tidy.

Common problems and how to fix them

• The puzzle is shifted by one or two places: a pinned post comes before it, another post slipped in between two tiles, or you have posted once or twice since. Pin no posts or exactly 3, post the tiles back to back (and later posts in threes), and use the grid reordering option (rolling out since June 2026) to move a misplaced tile.
• The joins don’t match in the grid: the tiles are 4:5 or square and the 3:4 thumbnails crop their sides. Export them again in 3:4.
• The carousel doesn’t join up: the slides were added out of order, or Instagram cropped them to another format. Select them in order starting from 1 and keep the same format for all of them: Instagram applies a single format to every slide in a carousel, usually that of the first one.
• Instagram crops the photo when you select it: in the post editor, check that the crop hasn’t switched to square and go back to the original format before sharing.
• Blurry tiles: the photo is too small for the full picture (a warning appears under the framing). Use the original photo rather than a screenshot or an image received through a messaging app, which are often downsized.

Privacy: your photo is processed only by your browser, on your device; nothing is uploaded, logged or stored, and closing the page erases everything. Limits: up to 5 rows (15 posts) or 10 slides; very large photos (over 50 megapixels) may be slow or fail on a phone; HEIC files only open in browsers that can read them, such as Safari. Instagram’s display (3:4 thumbnails, cropping) may change: check the preview in the app before posting.
