About Merge Images Online
Combine two or more images into a single picture, right in your browser. Place photos side by side, stack them vertically, or arrange them in a grid. Control the spacing, pick a background color (or keep it transparent), reorder images by dragging, and export as PNG or JPG. Nothing is uploaded — all processing happens locally on your device.

Frequently Asked Questions
How many images can I merge?
Up to 30 images at once. For a clean grid, 2 to 9 images usually works best.
Can I keep a transparent background?
Yes. Choose PNG as the output format and tick 'Transparent background'. Gaps and empty grid cells stay transparent. JPG does not support transparency.
Will my images be uploaded to a server?
No. Merging happens entirely in your browser using the HTML canvas, so your images never leave your device.
How are different image sizes handled?
Side-by-side matches heights, stacked matches widths, and grid fits each image inside a uniform cell while keeping its aspect ratio.
