Made Specifically for Photo Grids

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 Common Grid Size
  • 2x2 grid (4 photos) - the classic balanced square
  • 3x3 grid (9 photos) - the Instagram-style mosaic
  • 2x3 and 3x2 (6 photos) - rectangular grids
  • 2x4 and 4x2 (8 photos) - wide strip grids
  • 2x5 and 3x4 (10 or 12 photos) - memory-board grids
  • Custom grid builder for any rows and columns
Controls Tuned for Grids
  • Equal-cell auto-sizing across the whole grid
  • Adjustable gap between cells from 0 to 60 pixels
  • Uniform border color, thickness, and corner radius
  • One filter across every photo for tonal consistency
  • Cover, Contain, or Stretch fit mode per cell
Works Everywhere You Post
  • iPhone and Android browser support (no app install)
  • Instagram feed 1080x1080 - perfect for 3x3 grids
  • Stories and WhatsApp status 1080x1920
  • Facebook cover, YouTube thumbnail, Pinterest pin
  • 300 DPI print output for 4x6 and 5x7 photo cards

How to Make a Photo Grid Online in 3 Easy Steps

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.

Why Choose Pi7 as Your Photo Grid Maker

How Pi7 stacks up against the usual ways people make a photo grid.

vs. Mobile Photo Apps
Most mobile grid apps run ads, ask for broad permissions, and lock higher-quality export behind a subscription. Pi7 is a free website that works on iPhone and Android browsers with no install, no ads, and no subscription.
vs. Upload-Based Grid Tools
Other online grid makers upload your photos to their servers to assemble them. Pi7 builds the grid entirely in your browser, so your photos stay on your device throughout the whole process.
vs. Social Media's Auto-Grid
Uploading multiple photos to a social post auto-generates a grid with zero control over spacing, border, order, or aspect ratio. Pi7 gives you every grid control before you export a single finished image.
vs. Screenshot + Crop
Screenshotting photos next to each other leaves ragged edges and mismatched spacing. Pi7 snaps every cell to an equal size, with uniform gaps and pixel-precise alignment across the whole grid.
vs. Desktop Editing Software
Building a photo grid in a professional image editor means setting up guides, snapping layers, and managing spacing manually. Pi7 ships all eight grid sizes ready to go, with equal-cell sizing handled automatically.

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.
