How does an Instagram grid splitter work?

It loads your image into an HTML canvas, scales it to fit the chosen grid (for example three tiles wide by three tall), then crops each cell into its own square or 4:5 JPEG. When you re-upload the tiles in the right order they reassemble into one large picture across your profile grid.

In what order do I post the tiles?

Instagram puts your newest post in the top-left of your profile, so you must post in reverse. The ZIP names every file with both its final position (pos01 is top-left) and an upload number, and includes a HOW-TO-POST.txt explaining to post the highest upload number first and upload01 last.

Should I use square or portrait tiles?

Square (1:1) tiles match the classic Instagram grid exactly and are the safest choice. Portrait (4:5) tiles are taller and show more of your image per cell, but Instagram may crop the very top and bottom slightly in the grid thumbnail view.

What image size should I upload?

Upload the largest, sharpest image you have. The tool exports tiles at 640, 1080 or 1440 pixels wide. 1080px is Instagram's high-definition size and is recommended for a 3x3 grid, which means your source ideally should be at least 3240px wide.

Is my photo uploaded to a server?

No. Every step runs entirely in your browser using the canvas and JSZip libraries. Your image never leaves your device, and the ZIP is generated locally — there is no upload, account or watermark.

What is the difference between Cover and Stretch fit?

Cover crops your image to fill the grid's aspect ratio without distortion, trimming the edges that do not fit — this is recommended. Stretch squeezes the whole image into the grid shape with no cropping, which can distort it if your photo's proportions differ from the grid.

Instagram Grid Splitter

The Instagram Grid Splitter turns a single photo into a row or block of perfectly aligned feed tiles, so that when the tiles sit next to each other on your profile they reassemble into one large picture — the “puzzle feed” or “grid mural” look used by brands, photographers and creators to make a profile instantly eye-catching. Upload one image, pick a layout, and the tool slices it into individual square or portrait tiles, shows you exactly how the finished grid will look, and hands you a ZIP of every tile ready to post. It is built for anyone planning an Instagram feed who wants the seamless multi-post look without paying for a planning app.

How it works

When you upload an image it is decoded into an in-browser canvas. You choose a grid shape — a 3×3 block (nine tiles), a 1×3 panoramic row, or one of several other arrangements such as 2×3, 4×3, 3×1 and 2×2. The tool computes the combined target size (for a 3×3 grid at 1080px tiles that is 3240×3240 pixels), then draws your image onto that canvas using a Cover fit that crops the overflowing edges so nothing is distorted, or a Stretch fit that keeps the whole frame. Each grid cell is then cropped into its own tile and encoded as a high-quality JPEG.

Because Instagram displays your newest post in the top-left corner, posting order matters: you have to upload the tiles in reverse. The downloaded ZIP solves this for you — every filename encodes both the tile’s final position (pos01 is the top-left of the finished grid) and an upload number, and a HOW-TO-POST.txt file spells out the exact sequence. Everything runs locally; your photo is never uploaded.

Example

Say you have a wide landscape photo and want a striking 3×3 mural at the top of your profile. Upload the image, choose 3 × 3 grid, keep Square tiles and Cover fit, and set tile width to 1080. Click Split image and you get nine 1080×1080 tiles plus a live preview showing tile 1 top-left through tile 9 bottom-right. Download the ZIP and post upload09 first, working down to upload01 last — the nine posts snap together into your single landscape across the whole grid.

Layout	Tiles	Best for
3 × 3 grid	9	Full-screen profile mural
1 × 3 row	3	One panoramic banner row
2 × 3 grid	6	Two-row wide feature
3 × 1 column	3	Tall vertical strip

Every tile is generated in your browser — no numbers, names or images are ever uploaded or stored.
