Turn one photo into a
seamless Instagram grid.

GridSplit is a free browser-based Instagram grid maker. It splits one photo into 3, 6, or 9 seamless posts using a bleed-correction formula — eliminating the visible gaps that Instagram adds between grid tiles.

Instagram adds small gaps between grid posts on profile pages. Most grid splitters do a basic crop and ignore this, so seams appear between your posts. GridSplit overlaps each tile slightly into adjacent tiles to compensate, making your panoramic grid look perfectly seamless.

Each tile exports at 1080×1350px — the 4:5 portrait format Instagram has displayed grid posts in since 2025. GridSplit always exports at Instagram’s current grid size.

GridSplit supports 3 posts (1 row × 3 columns), 6 posts (2 rows × 3 columns), and 9 posts (3 rows × 3 columns).

GridSplit accepts JPG, PNG, WEBP, and HEIC. Upload via drag-and-drop or click to browse. There’s no file size limit enforced in the browser.

Check the crop when you upload to Instagram. Instagram’s uploader often defaults to a square (1:1) crop, particularly on desktop — and a square crop trims the bleed off both sides of every tile, which puts the seams straight back. At the crop step, choose the 4:5 portrait option so the full 1080×1350 tile is uploaded untouched. GridSplit’s tiles are already exactly Instagram’s grid size, so they never need cropping.

Post in numbered order — tile #1 first, then #2, and so on, finishing with your highest-numbered tile. Instagram puts the newest post top-left, so #1 ends up at the bottom-right and your final tile locks in the top-left. GridSplit shows a posting order guide after generating.
