A fast, private photo collage maker
Creating a visual story often requires more than a single image. This photo collage maker lets you combine photos into one cohesive layout directly in your web browser. Whether you are building a mood board, sharing a vacation recap, or creating a before-and-after comparison, you can arrange your images into a clean, professional grid in seconds.
Because the tool operates entirely locally, your files are never uploaded to a server or processed in the cloud. This means you can safely use this collage maker online for personal family photos, unreleased product shots, or confidential project images without worrying about data privacy. It also means the tool is incredibly fast—your collage updates instantly as you adjust sliders, with no loading screens or network delays.
How to use this photo grid maker
The tool is designed to be as intuitive as possible, handling the complex math of grid proportions automatically. Once you drop your images into the tool, you have full control over the final look:
Flexible Layouts. The tool offers a variety of grid configurations tailored for two to nine images. When you upload your files, the photo grid maker automatically selects a layout that matches your image count. You can easily switch to a different layout using the grid icons—from simple side-by-side splits and three-panel stacks to complex asymmetrical grids.
Optimized Sizes. Instead of guessing the right dimensions, you can choose from four standard canvas sizes:
- Square (1080×1080): The classic format, perfect for standard social media feeds and profile galleries.
- Portrait (1080×1350): A taller aspect ratio that maximizes screen real estate on mobile feeds.
- Story (1080×1920): A full-screen vertical format ideal for mobile stories, reels, and vertical video thumbnails.
- Landscape (1920×1080): A wide format suited for desktop viewing, presentations, and video backgrounds.
Custom Styling. You don't have to settle for rigid, blocky grids. The Spacing slider controls the breathing room (gap) between photos, allowing you to create thick borders or seamless, edge-to-edge designs. The Corners slider softens the edges of your images, giving your picture collage a modern, app-like aesthetic. Finally, the Background color picker lets you match the canvas behind your photos to your brand colors or the theme of your images.
Tips for the perfect picture collage
Understanding the crop. Because grid cells have fixed aspect ratios that rarely match your original photos perfectly, the tool automatically scales and center-crops your uploaded images to fill the space completely. This "cover" behavior ensures there are no empty gaps inside the layout.
Rearranging images. If an image doesn't look quite right in its current spot, you don't need to start over. Use the Swap button to cycle all images one position forward through the grid. If you want to experiment with entirely different arrangements, click Shuffle to randomize the placement of your photos instantly.
Handling empty cells. If you select a layout with more cells than the number of images you uploaded, the tool will fill the empty spaces with a clean, light gray placeholder. You can either use the "Add More" button to fill those spots, or switch to a layout that exactly matches your image count.
Working with different formats. If you are an iOS user, you can drop HEIC or HEIF photos directly into the tool without needing to convert them first. When you are happy with your design, you can export the final composition as a high-quality JPG (ideal for smaller file sizes) or a lossless PNG (best for crisp edges and solid background colors).
If you need to stitch images side-by-side without any cropping at all, try the Merge Images tool. To adjust individual photo dimensions before putting them into a grid, use Resize Image, or if you want to do the exact opposite and cut a large layout into individual posts, check out Split Image.
