What Is Image Merger?
Image Merger is a free online tool that lets you merge multiple images into one instantly. Whether you need to combine photos horizontally, vertically, or in a grid layout, this image combiner handles it all — right in your browser with zero server uploads.
Unlike desktop software that requires installation, our online photo merger works on any device with a web browser. Simply drag and drop your images, choose your preferred layout, adjust spacing and alignment, and download the merged result. It supports JPG, PNG, and WebP formats with no quality loss.
Why Use an Online Image Merger?
Combining images is one of the most common tasks in everyday photo editing. From stitching screenshots together for a bug report to creating a photo collage for social media, you need a quick and reliable way to merge pictures without firing up Photoshop or installing any app.
Our image combiner gives you three layout options — horizontal, vertical, and grid — so you can merge two photos side by side, stack them top to bottom, or arrange multiple images in a tiled grid. Every layout automatically aligns your images and lets you fine-tune spacing, background color, and output format.
Key Features of Image Merger
- Three layout modes — Merge images horizontally (left to right), vertically (top to bottom), or in a grid for collage-style results.
- Batch merging — Combine up to 20 images at once. Drag to reorder them before merging.
- Spacing and alignment — Add 0-50 px gaps between images and pick a background color for the gaps.
- Flexible output — Download the merged image as PNG (lossless) or JPG (smaller file size).
- 100% private — All processing happens locally in your browser. Your images never leave your device.
Popular Use Cases for Merging Images
People use our photo merger for a wide range of tasks:
- Social media collages — Combine multiple photos into a single post for Instagram, Facebook, or Twitter.

Image Merger vs. Other Tools
Compared to desktop apps like Photoshop or GIMP, Image Merger is purpose-built for one task: combining images fast. There is no learning curve, no installation, and no cost. Compared to other online tools, we offer grid layout support, batch merging of up to 20 images, and complete browser-side processing for maximum privacy. If you need to crop images into circles before merging, try our circle crop tool, or convert photos to grayscale before combining them.
Need a format-specific merger? Try our JPG merger with quality control, or our PNG merger with transparency support. You can also overlay images with adjustable opacity, or place two photos side by side for quick comparison.
