Grid Maker for Instagram — split one photo into 3×3 tiles
Split one large photo into a 3×3 grid (or 3×2, 3×1, 2×2) online: tiles in 1:1 / 4:5 / 3:4 ratios, full preview with cut lines, slices named in posting order, ZIP download. For Instagram profile grids and multi-post mosaics. Split locally in your browser — nothing uploaded.
A grid split cuts one large image into 3×3 (or other) tiles that reassemble into the full picture on your profile when posted in order — the classic Instagram profile-grid trick, also popular for WeChat Moments and Xiaohongshu mosaics. Upload a photo, pick a layout (3×3 / 3×2 / 3×1 / 2×2 / 2×3) and a tile ratio: besides classic 1:1 squares, 4:5 and 3:4 portrait ratios are supported (some feeds now default to portrait display, where 1:1 tiles get re-cropped). Preview the cut lines full-screen, then split and download a ZIP with slices named in posting order: publish post-01 first and the grid assembles perfectly. Everything runs locally in your browser; nothing is uploaded.

About grid splitting
- 3×3 / 3×2 / 3×1 / 2×2 / 2×3 layouts with full cut-line preview
- 1:1 / 4:5 / 3:4 tile ratios for modern portrait feeds
- Slices named in posting order + ZIP; local, no upload
- You must post in the post-01, post-02… order or the mosaic breaks
- Low-resolution sources are split at native size (never upscaled into blur)
- Feeds may re-crop individual tiles; the mosaic effect applies to profile / album views
Grid Maker FAQ
That is the posting order. Profile grids place the newest post top-left, so the bottom-right tile goes first and the top-left tile last. Publish post-01 through post-09 in order and the full picture assembles; filenames also carry row/col for double-checking.
Classic profile grids use 1:1, but some feeds now display portrait by default and may crop 1:1 tiles — 4:5 or 3:4 avoids that. Choose based on where the tiles will mainly be seen.
Up to 1080px wide (the social-platform standard), height per the chosen ratio; lower-resolution sources are split at native size — never upscaled into blur.
No — splitting and zipping run entirely in your browser; the image never touches a server.
