About the Image Splitter (Grid & Carousel)
Cut one image into pieces: a grid of rows and columns, tiles of an exact pixel size (sprite sheets, map tiles, print panels), or equal strips side by side or stacked. Two presets prepare posts for Instagram: a profile grid of 3 × N posts that line up as one big picture, and a seamless panorama carousel whose slides continue the picture as you swipe.
A live preview draws every cut and the number of each piece on your image, so you see the result before you save it. Pieces are numbered in the order you need — for the profile grid that is posting order, bottom right first — and download as one ZIP or one by one. Your image never leaves your device.
How to use it
- Choose, drop or paste an image (JPG, PNG, WebP, GIF or HEIC).
- Choose how to split it: Grid (rows × columns), Tile size (width × height in pixels), Strips, Instagram grid or Carousel. The dashed lines on the preview show the cuts, and the numbers the order.
- For the Instagram presets, drag the bright frame (or zoom) to choose the part of the image that is used.
- Pick the format and select Split image, then Download all (ZIP) or download pieces one by one. On a phone, Share or save can put them straight into your photos.
Examples
A 4000 × 5000 px image · Instagram grid · 3 rows
9 posts of 1080 × 1440 px, each cut from 1250 px of the image; file names start with the posting order (post 1 = bottom right)
A 6000 × 2000 px panorama · Carousel · 3 slides · Portrait 4:5
3 slides of 1080 × 1350 px cut edge to edge from the middle 4800 × 2000 px of the panorama
A 256 × 128 px sprite sheet · Tile size 32 × 32 · PNG
32 PNG tiles of exactly 32 × 32 px, numbered row by row
A 9000 × 3000 px banner · Strips · 3 side by side
3 panels of 3000 × 3000 px at full resolution
Common uses
- A 3 × N “puzzle” grid on an Instagram profile for a launch, an event or a portfolio.
- A wide panorama or a group photo as a carousel people swipe through.
- Cutting a sprite sheet or texture atlas into equal tiles for a game.
- Printing a large poster or banner in panels on ordinary paper.
- Splitting a scanned page or a long screenshot into parts.
Grid, tiles and strips
- Grid divides the image into equal rows and columns at its full resolution. When the size does not divide evenly, pieces differ by one pixel at most, and neighbouring pieces meet exactly — nothing is lost or repeated.
- Tile size cuts pieces of an exact size from the top-left corner, for sprite sheets, game maps and texture atlases. The pieces left over at the right and bottom edges can be kept smaller, filled to the full size (transparent or a colour) or left out; left-out areas are dimmed on the preview.
- Strips cut the image into equal vertical strips (side by side) or horizontal strips (stacked) — for printing a wide poster on several sheets, or splitting a photo in half.
Instagram profile grid
Instagram profiles now show posts as tall rectangles instead of squares (The Verge). This preset makes 3:4 posts of 1080 × 1440 px — the tallest shape Instagram keeps, at the 1080 px width it stores photos at (Instagram Help Centre) — three per row, so they line up as one picture. Instagram has not stated the tile shape on a help page that could be checked, so compare with your own profile before posting a whole grid.
The newest post shows first, at the top left, so the posts are numbered in posting order: post 1 is the bottom-right piece and the last one is the top-left piece. Post them one at a time, in order, as separate posts; pinned posts stay at the start of the grid and break the line-up while they are pinned. For classic 4:5 posts that still line up, use the Instagram Grid Maker.
Seamless panorama carousels
A carousel post can hold up to 20 photos and videos, and the shape you choose — square, portrait or landscape — applies to every item in the post (Instagram Help Centre). The carousel preset therefore cuts slides of one shape — 4:5 (1080 × 1350), 3:4 (1080 × 1440), 1:1 (1080 × 1080) or 1.91:1 (1080 × 566) — edge to edge, so the right edge of one slide continues on the left edge of the next as people swipe. Add the slides to one post in order, slide 1 first, and keep their shape when Instagram offers to crop.
Quality and formats
Grid, tile and strip pieces keep the image’s own pixels. Preset posts are resized to 1080 px wide; the tool says when the image is too small and posts would be enlarged. Same as the image saves JPG as JPG, WebP as WebP and other images as PNG (HEIC becomes JPG); JPG has no transparency, so transparent areas become white. Saved pieces carry no EXIF data such as the camera or the GPS location.
Limitations
- Up to 20 rows and 20 columns (400 pieces) in a grid, 2,500 tiles by size, 50 strips, 10 rows of grid posts and 20 carousel slides.
- Very large images are reduced to 64 megapixels on computers and 16 megapixels on phones and tablets so the browser does not run out of memory; the tool says when it does.
- Instagram may change how it shows grids and carousels; check the result on your own profile.
- The first 60 pieces are shown on the page; all of them are in the ZIP.

Frequently asked questions
Is my image uploaded?
No. The image is cut in your browser and the pieces are saved straight to your device. After the page has loaded once it works offline (HEIC photos in browsers other than Safari, and WebP in Safari, download a decoder or encoder from this site the first time).
In which order do I post an Instagram grid?
Post 1 first and the highest number last: post 1 is the bottom-right piece, because Instagram shows the newest post at the top left. The file names start with that number, so they sort in posting order.
How do I make a seamless carousel?
Choose Carousel, the number of slides and a shape (4:5 portrait takes the most room in the feed), drag the frame over the part of your panorama you want, then Split image. Upload all the slides in one post, in order.
How do I split an image into equal parts?
Use Grid with the rows and columns you need (for example 2 × 2 for four quarters), or Strips for equal strips in one direction. Pieces keep the image’s full resolution.
Can I cut tiles of an exact size?
Yes — choose Tile size and enter the width and height in pixels. Choose what happens to the leftover pieces at the right and bottom edges: keep them smaller, fill them to the full size, or leave them out.
Why are my grid posts blurry?
The image is smaller than the posts need: a 3-column grid needs 3240 px across for 1080 px posts, and 1440 px of height per row. The tool shows how much the posts are enlarged — use a larger image or zoom out.
