Open the Grid MakerPhoto Grids: Equal Cells, No Decoration, Just Photos
A grid is different from a collage. Every cell is the same size, the spacing is uniform, the alignment is exact. Pi7's grid maker is built around that idea, with grid-specific controls that make symmetry the default instead of something you have to fight for.

Every grid opens directly in the editor with cells already arranged. Pick the one that matches how many photos you have.
Three Steps from Photos to a Clean Grid
The grid-making flow from start to finish. No tutorial, no wizard, no account.
Pick your grid size
Choose from eight preset sizes above (2x2, 3x3, 2x3, 3x2, 2x4, 4x2, 2x5, 3x4) or open the Custom Grid builder if you need rows and columns outside the presets.
Drop photos into each cell
Drag JPG, PNG, or WebP files onto each cell, or tap to upload from your iPhone or Android camera roll. Drag-swap cells if the order is wrong, and crop each photo independently.
Tune spacing and export
Set the gap between cells, pick a background color, add a uniform border, and export. PNG keeps transparency, JPEG keeps file size small. 4x resolution option for print and retina screens.
Pi7 vs Bento and Magazine Layout Tools
How Pi7 stacks up against the usual ways people make a photo grid. Need text headlines or themed backgrounds instead of a clean grid? The 5 photo collage maker and 4 photos in one frame tools add editorial typography. For a 3x3 grid sized for the IG profile thumbnail, the Instagram collage maker presets the right dimensions.
Grid vs Mosaic vs Scrapbook: Three Layouts, Three Use Cases
A grid wins when the photos are equal in weight and the eye needs to scan them quickly. Inventory shots, product catalogues, before/after panels, screenshot tutorials, contact sheets - all of these read better as a uniform grid than as a varied mosaic. Equal cells signal equal importance; varied cells signal hierarchy.
The mosaic (some big, some small) is the right pick when one or two photos lead and the rest support - a magazine spread, a feature article, a hero-with-supporting-shots story. The scrapbook (rotated, overlapping, themed) is for emotional content where the layout itself is part of the message - birthdays, recaps, mood boards. Pick the grid when the answer to "is one of these photos more important?" is no. Pick the mosaic when the answer is one or two. Pick the scrapbook when the answer is none and the story is the vibe, not the hierarchy.
Grid Building Stays Local - No Photo Upload
Privacy is not an afterthought here - the whole tool is engineered around it. The photos that go into a grid are often everyday personal moments: product shots before a sale, screenshots for a tutorial, kid photos for a print. We do not think those should pass through a third party's server just so you can arrange them into a grid. So they do not.
Most online grid makers work by uploading your photos to a server, processing them in the cloud, then handing back the finished image. Pi7 does the opposite. Every photo you drop in is read locally by JavaScript and rendered to a canvas inside your own browser. The pixels never travel - not to us, not to a CDN, not to a third-party processor.
No Account, No Upload, No Watermark
No signup, no email, no account creation, no waiting on an upload bar. Open the tab, build the grid, export the image, close the tab - and the session is gone. There is no copy of your photos on a server somewhere being indexed, sold to model training, or sitting in an archived backup.
The practical knock-on benefits: it is fast (no upload time even for a full 6x6 grid of high-resolution photos), it works offline once the page is loaded, there is no rate limit because there is no shared backend to throttle, and no watermark on the export because there is no premium tier to upsell into.
Frequently Asked Questions
What grid sizes are available?
Pi7 has eight preset grids: 2x2 (4 photos), 3x3 (9 photos), 2x3 and 3x2 (6 photos), 2x4 and 4x2 (8 photos), 2x5 (10 photos), and 3x4 (12 photos). If you need a size outside those presets, the Custom Grid builder lets you set any number of rows and columns.
Can I make a 3x3 grid for Instagram?
Yes. Open the 3x3 grid template and set the canvas to the 1080x1080 Instagram preset. Each of the nine cells auto-sizes to exactly 360x360 pixels with adjustable spacing between them. For a scroll-stopping single-post Instagram grid, this is the classic format.
Can I make a photo grid on iPhone or Android?
Yes. Pi7 runs in iOS Safari, Chrome on iPhone, Chrome on Android, Samsung Internet, and every other modern mobile browser. The same grid sizes, controls, and 4K export are available on phone as they are on desktop, with no separate app to install.
Can I adjust the gap between grid cells?
Yes. The gap slider goes from 0 to 60 pixels and applies uniformly to every cell in the grid. You can also set the background color that shows through the gap, add a uniform border around each cell, and round the corners for a softer look.
Is the photo grid maker really free?
Yes, completely free. No signup, no trial, no premium tier, no watermark on the exported image. Every grid size, every control, and the full 4K export are available without an account. Pi7 stays free forever.
