What does this tool do?
This free image merger combines two to ten images into a single picture — stacked vertically, side-by-side horizontally, or in a neat grid. Reorder them, set spacing and background color, and download the combined result as one JPG or PNG. Everything happens in your browser.
How does the image merger work?
The merger computes a combined canvas size from your layout choice (aligning widths for vertical stacks, heights for horizontal strips), draws each image in order with your chosen gap and background fill, and exports the composite via Canvas toBlob at full resolution.
Frequently Asked Questions
What happens if my images are different sizes?
The merger normalizes them intelligently: in a vertical stack every image is scaled to the same width; in a horizontal strip, to the same height. Proportions are always preserved — nothing gets stretched or squashed.
What are common uses for merging images?
The classics: before/after comparisons for fitness or renovation posts, side-by-side product option sheets, screenshot sequences for tutorials and bug reports, photo strips from events, and stitching tall chat screenshots into one shareable image.
Is the image merger really free?
Yes — 100% free with no hidden charges, trial limits, or premium tiers for core features. No account or email needed. The site is supported by non-intrusive display ads, which keeps every tool free for everyone.
Are my files private when using the image merger?
Completely. The image merger processes everything locally in your browser — your files are never uploaded to any server. When you close the tab, everything is gone. This makes it safe for confidential documents, client work, and personal photos.
Does the image merger work on mobile phones?
Yes. It's built mobile-first and works on any modern phone browser — iPhone (Safari) and Android (Chrome) included. You can pick files straight from your camera roll and download results directly to your device.
Do I need to install any software to use the image merger?
No. The image merger runs entirely in your web browser — no downloads, extensions, or signup. Open the page, use the tool, download your result. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
