What Is the IMG369 Image Splitter?
Image Splitter slices a photo into an equal grid of pieces, the layout you need for an Instagram grid post that spans multiple squares, a jigsaw-style puzzle graphic, or splitting a wide banner into printable pages. Pick a grid size and download every piece at once.
It's the reverse operation of IMG369's Image Collage Maker: that tool combines several photos into one grid image, this one takes a single photo and cuts it apart into pieces.
How It Works
Your photo is drawn onto a canvas and divided into equal-sized tiles based on the grid you choose, using the Canvas API entirely in your browser. Each tile is generated as its own image, downloadable individually or all together in a single ZIP file. Nothing is uploaded to a server.
Getting an Instagram Grid Post Right
The most common mistake with a split grid post isn't the splitting itself, it's the upload order. Instagram's profile grid fills left to right, then wraps to the next row, but a 3x3 split image needs to be posted in a specific sequence, generally the bottom-right piece first, working backward, so that once all nine posts exist, they read correctly as one image when viewed on the profile grid (since each new post pushes older ones down). Check this tool's numbered pieces against a quick sketch of your target grid before posting anything, since fixing the order after several pieces are already live means deleting and reposting. A source photo that's already close to a 1:1 or a clean multiple aspect ratio splits more evenly than an oddly-cropped one, worth cropping first with IMG369's Image Cropper if the proportions are off.
Common Uses
Creating a multi-post Instagram grid layout from one wide photo, splitting a banner or poster into individually printable pages, breaking an image into tiles for a puzzle-style design project, or dividing a large diagram into printable A4 sheets that get taped together afterward.
Tips for Best Results
For an Instagram grid post, use a 3x3 or 1x3 grid depending on how many posts you want the image to span, and upload each numbered piece in order starting from the top-left. A wide 2x1 or 1x2 split works well for splitting a landscape banner into two printable halves.
IMG369 vs. Other Ways to Split a Photo Into a Grid
Dedicated Instagram grid apps like Preview or Panoramic handle the posting-order logic for you and are worth it if you post grid layouts often, but they're extra apps to install for an occasional one-off split. Manually cropping each piece in Photoshop works but requires calculating exact pixel boundaries by hand for each tile, tedious and error-prone past a simple 2x2. IMG369 calculates the grid automatically and numbers every piece in reading order, right in the browser.

Summary
IMG369's Image Splitter slices a photo into a numbered grid of equal pieces for Instagram posts, printable pages, or puzzle graphics, entirely inside your browser with no upload and no signup. It's the mirror image of the Collage Maker: combine several photos into one there, cut one photo into several here. The sections above cover how to get the Instagram posting order right; the FAQ below covers grid sizes and download options.
Frequently Asked Questions
Is the Image Splitter really free?
Yes. There's no signup, no watermark, and no limit on how many photos you split. Everything runs on your own device.
Does my photo get uploaded anywhere?
No. The photo is sliced into pieces using the Canvas API entirely in your browser. Nothing is sent to a server.
What grid sizes can I use?
Pick from common presets like 2x2, 3x3, or a 1x3 and 3x1 strip, covering the most common Instagram grid post and puzzle-piece layouts.
How do I download all the pieces?
Click "Download All as ZIP" to get every piece in one file, or click an individual piece to download just that one.
In what order are the pieces numbered?
Left to right, top to bottom, the same reading order as the grid itself, so piece 1 is always the top-left tile.
