Image Collage Maker — Create Photo Collages Instantly

Need to combine multiple photos into a single image? Our Image Collage Maker lets you upload 2-12 images, choose from 11 grid layouts, customize spacing and corners, and download a polished collage — all processed entirely in your browser.

Grid Layouts

The collage maker offers 11 pre-designed grid layouts to fit different needs:

  • 2-image layouts: Horizontal (side by side) or Vertical (stacked)
  • 3-image layouts: 3 Horizontal, 3 Vertical, or combinations
  • 4-image layouts: 2×2 grid (classic square layout) or 4 Horizontal
  • 6-image layouts: 3×2 or 2×3 grids for medium collections
  • 9-image layouts: 3×3 grid for Instagram-style compositions
  • 12-image layouts: 4×3 grid for large photo collections

Customization Options

Canvas Size

Set any width and height from 200 to 4000 pixels. Common sizes include 1200×1200 (Instagram square), 1200×628 (Facebook/Twitter), and 2400×3000 (portrait print).

Spacing

Control the gap between images from 0 (no gap) to 50 pixels. A small gap (4-8px) gives a clean, modern look. Zero spacing creates a seamless mosaic effect.

Corner Radius

Round the corners of each image cell from 0 (sharp) to 50 pixels. This adds a polished, app-like aesthetic to your collage.

Background Color

Choose any color for the background visible between cells. White is classic; dark colors create a dramatic look. Match your brand or social media theme.

Smart Cover-Fit

Images of different sizes and aspect ratios are automatically handled using cover-fit cropping:

  • Each image fills its cell completely — no letterboxing or stretching
  • The image is centered, and excess is cropped from edges
  • Aspect ratio is always preserved

Common Use Cases

  • Social media posts: Combine multiple photos into a single shareable image
  • Before/after comparisons: Place two images side by side
  • Event recaps: Showcase highlights in a grid
  • Product showcases: Display multiple product angles or variants
  • Photo journals: Create visual stories from a series of photos

Privacy and Security

All image processing uses the HTML5 Canvas API directly in your browser. No images are uploaded, no data is transmitted. Your photos remain completely private.

Frequently Asked Questions

Is my data safe?

Yes. All image processing happens 100% in your browser. No images are uploaded to any server.

How many images can I use?

You can upload between 2 and 12 images. Choose a layout that matches your image count — extra cells will remain empty.

How does cover-fit work?

Each image is automatically cropped to fill its cell while maintaining aspect ratio. The image is centered and any excess is trimmed from the edges.

Can I reorder images?

Currently, images appear in upload order. You can remove an image and re-upload to adjust the order.

What resolution should I use?

For social media: 1200×1200 or 1200×628. For print: use larger dimensions (2400×3000+). The tool handles any size up to browser memory limits.
