How do I merge multiple images into one online?

Upload two or more images using the upload area above. Select how you want to merge them — side by side (horizontal), stacked (vertical), or in a grid layout. Adjust spacing and alignment settings, then click Merge. The combined image is generated instantly and can be downloaded as a PNG or JPG.

Can I control the layout when merging images?

Yes. Our image merger offers multiple layout options: horizontal (images placed side by side), vertical (images stacked on top of each other), and grid (2×2, 3×3, or custom grid arrangements). You can also control the spacing between images, background color, and whether to resize images to a uniform size before merging.

What image formats can I merge?

You can merge JPEG, PNG, WebP, GIF (first frame), and BMP images. You can even mix different formats — for example, merge a JPG photo with a PNG logo that has a transparent background. The output can be downloaded as PNG or JPG.

Is there a limit to how many images I can merge?

Typically you can merge 2-10 images in a single operation depending on your browser's available memory and the image sizes. For very large images (over 10MP each), merging many files at once may be slow. For batch merging of many files, a desktop application like Photoshop or GIMP may be more suitable.

Can I create a photo collage with this tool?

Yes. Using the grid layout option, you can create simple photo collages by arranging multiple photos in a uniform grid. For more complex collages with different-sized panels, custom borders, and text overlays, consider using our Image Collage Maker tool.

Are my images uploaded to a server when merging?

No. All image merging is performed entirely in your browser using the HTML5 Canvas API. Your images never leave your device — they stay completely private throughout the process.
