## About

Photo Collage Maker combines multiple photos into one composed image — a grid of your choosing with adjustable spacing and background, exported as a single JPG or PNG. Unlike a folder of loose pictures, a collage tells the whole story in one glance: the trip, the before-and-after, the full product lineup. Everything renders locally in your browser with the canvas API, so the photos are never uploaded anywhere, and each cell exports at 640 pixels for a sharp result at typical share sizes.

## Key features

- Six grid layouts from 1×2 up to 3×3
- Adjustable spacing and background color (or transparency)
- JPG and PNG export at 640px per cell
- Photos fill in order — remove and re-add to rearrange
- Runs 100% in your browser; photos never leave your device

## How to use

1. **Add your photos** — Drag or pick up to 9 images from your device.
2. **Choose the layout** — Pick a grid, then tune spacing and background color.
3. **Download the collage** — Export as JPG or PNG with one click.

## FAQ

### How do I make a photo collage online for free?

Add your photos to PdfPixels Photo Collage Maker, choose a grid layout, adjust spacing and background, and download the finished image. It is free, needs no account, and runs in your browser.

### How many photos can a collage hold?

Up to 9, matching the 3×3 layout. Smaller layouts such as 2×2 use the first photos in the list.

### How do I change the order of photos in the collage?

Photos fill the grid left to right, top to bottom, in the order shown in the thumbnail strip. Remove a photo and re-add it in the right position to rearrange.

### Are my photos uploaded to a server?

No. Collages are composed with the browser’s canvas API on your device — nothing is uploaded, and the tool works offline once the page has loaded.
