Grid-it for Instagram is a free photo gridding app designed to help Instagram users create stunning montages and split photos across carousels. With Grid-it, you can select from four different grid options: 3x1, 3x2, 3x3, or 3x4. The app keeps your photo splits in high resolution and doesn't reduce the quality of your photos after splitting.

Using the app is easy. Simply choose the grid option you want to use, add a photo, and then rotate, crop, and zoom it to size. Once you're done, Grid-it will split the image into Instagram-sized tiles and guide you through the order to share each tile to Instagram.

Grid-it also recently added the ability to split your photo across an Instagram carousel, providing even more creative options for your Instagram account. You can check out some examples by searching for @griditforinstagram within Instagram.

Please note that Grid-it is in no way associated with Instagram. While the app is free to use, it does contain ads. However, you can remove these ads by unlocking the ad-free version via in-app purchase.
