Frequently Asked Questions

How do I merge images side by side?

Upload your images (2 or more), select "Horizontal" direction, and click Merge Images. The tool will align all images by their tallest height and place them side by side with your chosen gap spacing.

What does the gap setting do?

The gap adds spacing between each image in pixels. A small gap (2-5px) creates a clean divider effect. For seamless panoramas, set gap to 0.

Can I reorder images after uploading?

Yes. Each uploaded image has an up and down arrow to change its position in the merge order. The final image will arrange them from left to right (horizontal) or top to bottom (vertical) in the order shown.

What happens if images have different sizes?

For horizontal merge, all images are scaled to the same height (the tallest one). For vertical merge, all images are scaled to the same width (the widest one). Aspect ratios are preserved.

Is my image uploaded to a server?

No. All processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device, making this 100% private and secure.

Can I merge more than two images?

Yes, you can merge any number of images (2 or more). There's no hard limit, but very large numbers of high-resolution images may affect browser performance.
