What is Image Grid Splitter?

The Image Grid Splitter divides a single image into a grid of tiles, great for Instagram carousel posts or multi-panel layouts. Pick an even grid or drag the split lines to place each cut exactly where you want, then download numbered tiles ready to upload in sequence.

By default tiles export at the largest size that divides evenly into the source: a 3000 px wide image split 3 by 3 yields nine 1000 px tiles, with remainder pixels along the right and bottom edges trimmed. You can also drag the grid lines on the preview to make tiles different sizes, set an exact pixel width and height per tile, or add spacing so each tile gets a clean margin. Pick PNG for lossless detail, or JPEG or WebP with a quality slider for smaller files. Each tile is named by its row and column position, downloadable one at a time or bundled into a single ZIP archive.

How to use

1. Step 1 — Upload the image you want to split by dragging it onto the canvas or clicking to browse.
2. Step 2 — Select your grid size: 2x2, 3x3 (most popular for Instagram), 4x4, or enter a custom grid dimension.
3. Step 3 — Preview the grid overlay on your image, then download all tiles as individually numbered files or as a ZIP archive.

When to use

• Posting an Instagram carousel from a wide panorama that scrolls panel by panel.
• Turning one large photo into a 3 by 3 mosaic for an Instagram or Pinterest grid layout.
• Printing posters in pieces on a home printer that cannot handle the full sheet.

Result

Upload a panoramic cityscape and select 3x1 (3 columns, 1 row) to create an Instagram carousel. The tool splits it into 3 sequential panels that line up edge to edge when swiped.

FAQ

Will the tiles line up perfectly after upload to Instagram?

Yes, as long as the original image's aspect ratio divides cleanly. Square inputs map best to NxN grids. For a 1x3 strip carousel, start with a 3:1 panorama so each tile becomes a 1:1 square that Instagram displays without cropping.

What's the maximum grid size I can split into?

Up to 10 rows by 10 columns. That's 100 tiles from one image. Beyond that the tiles become small enough that the visual benefit is lost, and Instagram's nine-slot preview can only fit so much before the pattern breaks.

Does splitting reduce the image quality?

Each tile is a direct pixel-perfect crop of the original area. There's no resampling, no extra compression artifacts, and no quality loss when you stay on PNG. Switch to JPEG or WebP if file size matters more than maximum fidelity, and use the quality slider to tune the trade-off.

Can I split into uneven rectangles, like 3 columns by 1 row?

Yes. Use the custom rows and columns inputs to set any combination from 1x1 up to 10x10. A 3x1 split is perfect for the classic three-panel Instagram carousel where the post unfolds horizontally as you swipe.

What happens to the leftover pixels when dimensions don't divide evenly?

On an even split the remainder is trimmed from the right and bottom edges so those tiles share identical dimensions. If your image is 1001 pixels wide split into three columns, the last pixel is dropped and each tile becomes exactly 333 wide. Drag the split lines yourself and tiles can have different sizes on purpose.
