Photo Collage Grid Maker

Combine up to 9 photos into a collage using multiple layout templates. Set padding, corner radius, background color, and output resolution, then download as PNG.

About Photo Collage Grid Maker

Photo Collage Grid Maker lets you arrange up to 9 images into a polished collage using six pre-designed layout templates — a classic 2×2 grid, a dense 3×3 grid, a featured 1-large + 2-small vertical split, a 1-large + 3-small panel, a 4-photo horizontal strip, and a triptych. The tool uses the HTML5 Canvas API entirely in your browser: no files leave your device and no server processing is involved. Each template is defined as a set of proportional cells, so the output scales cleanly to 800 px, 1200 px, or 2000 px wide. You can adjust gap padding (0–20 px), round the corners of each cell (0–20 px radius), and pick any background color. Missing image slots are filled with a gray placeholder so you can render partial layouts. Download the finished collage as a lossless PNG.

Tips

  • Pick 0 padding and the 3x3 grid for a seamless tiled-mosaic look popular on Instagram puzzle feeds.
  • Set 8–12 px corner radius and 12 px padding for a modern card-grid aesthetic that matches Material design systems.
  • Use the 1-large + 3-small panel layout for hero-style storytelling where one image leads the composition.

Frequently Asked Questions

How many photos can I add?▾
Up to 9 photos. Slots with no image assigned display a gray placeholder so the layout still renders cleanly.
What output formats are supported?▾
PNG only — it is lossless and handles transparent backgrounds (if you choose a transparent-look color) well for print and digital sharing.
Can I use photos from my phone?▾
Yes. On mobile browsers you can select photos from your camera roll via the file picker. The tool works on all modern mobile browsers.
Does the tool upload my images?▾
No. All processing runs locally in your browser using the Canvas API. No data is sent to any server.
What is the maximum output resolution?▾
2000 px wide. Height is determined by the aspect ratio of the chosen template. For a 1:1 template the output is 2000×2000 px.
Can I mix portrait and landscape photos?▾
Yes. Each image is cover-fitted (scaled and centered) into its cell, so orientation differences are handled automatically.
Does the tool watermark my output?▾
No. The output is a plain PNG of your photos arranged in the chosen layout — no logos, watermarks, or branding.
Are large photos automatically downscaled?▾
Yes. Each image is rendered at the cell's pixel dimensions in the final canvas, so very large source photos are downscaled by the canvas during composition. Quality remains crisp at typical output sizes.

Glossary

Cover fit
Scaling an image so it fills the entire cell while maintaining aspect ratio, cropping any overflow — like CSS object-fit: cover.
Padding
The gap in pixels between each image cell and between cells and the canvas edge.
Corner radius
The amount in pixels by which the corners of each image cell are rounded.
Triptych
A three-panel layout where images are arranged side by side in equal vertical strips.
Layout template
A predefined set of proportional cells that scales to any output width while keeping spatial relationships consistent.
Aspect ratio
The width-to-height ratio of the final canvas — determined by the chosen template and held constant when scaling output width.
Pixel density
The pixel count per unit of physical space when printed — higher output widths give sharper print results.
