Free Online Photo Collage Maker — Create Stunning Grid Layouts

The Photo Collage Maker lets you combine multiple photos into beautiful grid layouts directly in your browser. Upload up to 9 images, choose from five layout templates, customize spacing, background color, and corner radius, then download a high-resolution PNG collage. Everything runs locally — your photos are never uploaded to any server.

How the Collage Engine Works

The collage is rendered using the HTML5 Canvas API. When you select a layout template, the canvas is divided into grid cells according to the template's structure. Each uploaded image is drawn into its assigned cell using drawImage with object-fit-cover-like cropping: the image is scaled to fill the cell completely while maintaining aspect ratio, and any overflow is centered and clipped. This ensures every cell is fully covered without distortion, regardless of the original image proportions.

Layout Templates Explained

Five layout templates are available, each designed for different use cases:

• 2-Grid — Two images side by side, split vertically. Perfect for before/after comparisons or pairing two related photos.
• 3-Grid — One large image on the left with two smaller images stacked on the right. Ideal for featuring one hero image with supporting shots.
• 4-Grid (2x2) — Four equal squares. The classic grid layout for showcasing a set of related images with equal emphasis.
• 6-Grid (2x3) — Six cells in a 3-column, 2-row arrangement. Good for product collections or event photo sets.
• 9-Grid (3x3) — Nine equal cells in a 3x3 grid. Popular for Instagram multi-post sequences and comprehensive photo collections.

Output Size Presets

Three output size presets are tailored for common use cases. The 1080x1080 Instagram preset creates a perfect square for Instagram feed posts. The 1200x630 OG Image preset matches the recommended Open Graph image dimensions for link previews on Facebook, Twitter, LinkedIn, and messaging apps. The 1920x1080 Desktop preset creates a full HD landscape image suitable for presentations, desktop wallpapers, and web banners.

Customization Options

Fine-tune your collage with several design controls. The spacing slider adjusts the gap between grid cells from 0px (no gap, seamless grid) to 20px (visible borders). The background color picker sets the color visible in the gaps and borders. The corner radius slider rounds the corners of individual image cells from 0px (sharp corners) to 20px (noticeably rounded). These options combine to create collages ranging from tight professional grids to casual designs with rounded photos on colored backgrounds.

Image Arrangement

After uploading, images fill the grid cells in upload order. To rearrange, click on any cell in the preview to select it (highlighted with a border), then click another cell to swap the two images. This interaction lets you fine-tune the composition without re-uploading files. If you upload more images than the layout requires, the extra images are available for swapping into active cells.
