This Instagram grid maker splits one image into a 3-column profile grid and numbers each tile in the order you should post it. It runs in your browser, is free, needs no sign-up, and nothing is uploaded, so your artwork stays on your device.
If you searched for a grid maker for Instagram, an image splitter for Instagram, or a free Instagram grid maker app, this is that tool without the install. It works on a phone or a computer, wherever you have a modern browser.
How to use the Instagram grid maker
- Choose the image you want to split. It is opened locally in your browser and is not sent anywhere.
- Let the tool divide it into a 3-column grid. Each tile is numbered in posting order.
- Check the preview and make sure the important parts of your picture fall where you want them across the tiles.
- Save the numbered tiles to your device.
- Post the tiles to Instagram in the order of their numbers, so the full picture assembles on your profile.
Menus and buttons on the Instagram side can differ by app version, so look for the usual new post option and pick each tile in turn.
Why the numbers matter
Instagram shows your newest post at the top left of the grid. That means the last piece of the picture has to go up first. The numbering in this tool follows posting order, so you do not need to work out the reverse sequence yourself. Post tile 1, then tile 2, and so on.
Tips for good results
Start with a large, clean source image
Instagram stores photos at a maximum width of 1080 px (wider photos are sized down to 1080 px). Smaller photos are also adjusted: 320 px (smaller photos are enlarged to 320 px). Ads Guide: 500 px minimum for feed ads.. A source that is large enough keeps each tile sharp after the split, because every tile is only a part of the whole picture.
Plan around the three columns
A 3-column grid works best when your design is built for it. Keep faces, text and logos away from the lines where tiles meet. If a word or an eye sits right on a seam, it will look broken when someone opens a single post.
Pick a shape that matches your posts
The tool gives you tiles for a profile grid, and each tile is posted like any other photo. Instagram supports a range of 1.91:1 to 3:4. Unsupported ratios are cropped. Common choices for posts include:
| Shape | Size | Ratio |
|---|---|---|
| Square | 1,080 × 1,080 px | 1:1 |
| Portrait | 1,080 × 1,350 px | 4:5 |
| Tallest portrait | 1,080 × 1,440 px | 3:4 |
| Landscape | 1,080 × 566 px | 1.91:1 |
Neither official Instagram page names one recommended pixel size for organic posts, so treat these as sensible options within the supported range rather than a rule.
Keep each tile useful on its own
People also open single posts from search, tags and the feed. A tile that is only a blank patch of sky can feel odd there. Add a little texture, color or detail so a single tile still looks intentional.
Post in one sitting
If you upload tiles over several days, your profile looks unfinished in the meantime. Queue all tiles, then post them back to back in numbered order.
Need more control?
For custom rows and columns, try the Image Splitter. If you want to split a wide image into swipeable slides instead, use the Instagram Carousel Splitter.
Where the result works and where it may not
Where it works well
The tiles are ordinary image files, so they work as normal Instagram posts. The accepted file types for posts are JPG, PNG, according to Meta’s Ads Guide. The Instagram Help Center does not list file types for organic photos, so if an upload is refused, try another format and check the app’s current guidance.
The result is also useful anywhere you want a picture cut into evenly sized parts, such as a mockup preview or a design review.
Where it may not work as expected
- Cropping. Instagram crops ratios it does not support. Stay inside 1.91:1 to 3:4. Unsupported ratios are cropped.
- Grid view differences. How the profile grid crops tiles can change between app versions and between views. Always check your profile after posting, and do not assume every viewer sees the same crop.
- Other people’s views. The seamless picture only appears on your profile page. In the feed, each tile is a separate post.
- Text in your bio or captions. If you pair the grid with styled text, some Unicode fonts show as empty boxes in certain apps. Keep important text readable in plain characters. See Instagram Fonts for what to watch for.
- Carousels and stories. A grid is for the profile page. Carousels follow their own rules, such as 20 photos and videos, and the chosen orientation applies to every slide. Stories and Reels use a vertical canvas of 1,440 × 2,560 px, so a grid tile is not the right format for them.
Related sizes
If you are planning more than the grid, these pages give exact sizes:
- Instagram post size for the full post ratio range and notes.
- Instagram carousel size for slide shapes. A slide can be 1,080 × 1,350 px in portrait or 1,080 × 1,080 px in square.
- Instagram story size for the vertical canvas of 1,440 × 2,560 px and its safe area.
- Social Media Image Resizer if you need one image in several formats.
Privacy and cost
The tool is free, with no account and no watermark requirement described here. Because it runs in the browser, your image is processed on your device and is not uploaded.
