Photo Collage Maker: Combine Photos into a Grid
Combine multiple photos into a grid collage. Choose columns, gap, fit mode, and download as PNG or JPG.
Quick presets
Add images above to see a preview.
Upload several photos and arrange them into a grid collage with adjustable columns, gap width, background color, corner radius, and cell fit mode. Cover crops each photo to fill its cell, while contain fits the whole image with the background showing through. Download the final collage as PNG or JPG. All rendering happens locally on a canvas in your browser.
Photo collages are a standard format for social media posts, family albums, product showcases, and event recaps. Building one manually in image editing software means managing layers, aligning cells by hand, and applying clip masks one at a time. This tool generates the grid automatically: you set the column count, the gap between cells, and the background color, and the canvas math does the rest.
Cell sizing is uniform. Each cell is square and sized from the output width you specify, so a 1200px output with 3 columns and 8px gaps produces 381px cells. The cover mode scales and center-crops each photo to fill its cell completely, which looks clean when photos have different aspect ratios. The contain mode scales each photo to fit entirely within the cell with the background filling the letterbox area, which preserves the full frame.
Corner radius clips each cell independently before compositing, so the rounded corners apply only to the photo inside the cell, not to the whole canvas. You can mix a tight radius for a modern card look or leave it at zero for a classic grid. Output width is capped at 4000px to avoid browser memory issues with very large canvases.

Download the collage
Choose PNG for lossless output or JPG with a quality slider for smaller files. Click Download and the finished collage saves to your device.
Social media grid posts
Combine product shots or event photos into a single square or portrait grid image sized for Instagram or Twitter without uploading originals to a third-party service.
Family and travel albums
Turn a set of trip photos into one printable collage page, adjusting the gap and background color to match the album style.
Product showcase
Arrange multiple angles of a product into a 2x2 or 3x3 grid for a listing, pitch deck, or catalog page where a single composite image is needed.
Before-and-after comparisons
Place two or four images side by side in a horizontal strip or 2x2 grid to show changes, progress, or design iterations in one frame.
Are my photos uploaded anywhere?
No. All processing happens in your browser using the HTML Canvas API. Your photos never leave your device and no data is sent to any server.
What layouts are supported?
You can set 1 to 5 columns manually, or use the presets: 2x2 (2 columns), 3x3 (3 columns), horizontal strip (1 row, all photos side by side), and vertical strip (1 column). Rows are derived automatically from image count and column setting.
What is the difference between cover and contain?
Cover scales each photo until it fills the cell and center-crops anything outside the boundary. Contain scales the photo to fit entirely within the cell and fills any remaining area with the background color.
What output formats are available?
PNG for lossless output, or JPG with an adjustable quality slider (10-100%). PNG is better for screenshots or images with sharp lines; JPG produces smaller files for photos.
Is there a limit on how many photos I can add?
There is no hard count limit, but very large numbers of high-resolution photos can consume significant browser memory. For best results keep output width at or below 2400px when combining many images.
