Instagram Grid Maker

Drop your image into the tool, pick a grid (3, 6, 9, 12, 15 or 18 images) and a format, frame it by dragging and zooming, then download the images. They are numbered in the order to post them.

Each image is 1080 pixels wide, the width Instagram keeps. In 3:4, each image is 1080 × 1440 px, so the ideal source is 3240 × 1440 px for one row, 3240 × 2880 px for two rows and 3240 × 4320 px for a 3 × 3 grid. An image with another shape can be framed in the tool.

From what we see since early 2025, yes: the profile shows vertical 3:4 tiles instead of the old squares. Instagram does not describe it in any help page. So the tool offers 3:4, which lines up exactly, along with 4:5 and square, and the preview shows what the profile keeps.

From #1 to the last one. Instagram puts the newest post at the top left of the profile, so #1 ends up at the bottom right and the last one at the top left. The preview shows these numbers on each tile.

Yes. A row of three 3:4 images is close to 16:9, so the tool only trims a little from the top and bottom, and you choose what to keep. To keep everything, pick “Whole image”: the rest is filled with the color of your choice.

No. Each image is a separate post. A carousel only shows its first image on the profile, according to Instagram’s help center, so the mosaic would not appear. To split a photo into swipeable slides, use Kreatoai’s Instagram carousel splitter instead.

They are created 1080 pixels wide as high-quality JPEGs: that is what Instagram keeps, and it recompresses every image anyway. A very large image is first scaled down to stay smooth on your device, with no visible difference once posted.

No. Everything happens in your browser: the image never leaves your device, and nothing is kept when you close the page.

Yes. On a phone, the “Save to my phone” button puts the images in your photos when your browser allows it; otherwise, download them one by one or as a ZIP.

Yes: no sign-up, no watermark and no usage limit.
