Design for nine posts, not one sliced poster
Keep the main subject readable across the full image, but ensure no face or critical word sits directly on a guide. Each square will also appear alone in followers' feeds, so edge tiles need enough visual meaning to stand independently.
Preview the profile before downloading
Upload one high-resolution JPG, PNG or WebP, choose 3×3 and position the crop. The guides represent exact cut lines. Review the profile preview at small size as well as the detailed crop.
Use the numbered publishing order
The newest Instagram post appears first in the profile grid, so the assembled image must be published in reverse reading order. Download the ZIP and begin with file 01, the bottom-right tile. File 09, the top-left tile, is posted last.
Plan the transition
A nine-post reveal temporarily dominates a profile. Prepare captions, timing and any existing pinned posts before publishing. The Grid Maker handles image order, not account state or scheduling.
Save the unsplit campaign artwork. The ZIP contains delivery tiles, not a replacement for the original.
