Merge Images into One (Grid Collage)
Merge multiple images into one online — side by side, stacked, or in a grid collage with adjustable spacing and background.
How to use Merge Images / Collage
Add two or more images and choose a layout: a single row, a single column, or an automatic grid. Every image is fitted to a uniform cell so mixed sizes still line up cleanly, with adjustable gap and background color. Before/after comparisons, step screenshots and photo strips are all a ten-second job.
- Drop your files into the box above, or click it to browse. You can also paste from the clipboard.
- Adjust the options to taste — the defaults are sensible for most cases.
- Press Merge and watch the progress bar; everything runs on your device.
- Download your result — individually, or as a ZIP when there are several files.
Like every tool on ImageCompressorKits, this runs 100% in your browser: your file is never uploaded to any server, which makes it safe to use even with private documents — and it keeps working if you go offline after the page loads.
Frequently asked questions
Can I control the order of images?
Yes — images appear in the order you add them, and you can remove and re-add to rearrange. The live preview shows the exact final layout.
What resolution is the merged result?
Each cell is sized from the largest image's dimensions (capped for sanity), so quality stays high. Compress the result afterwards if you need a smaller file.
Is this tool really free?
Yes — completely free, with no signup, no watermark, and no file limits beyond what your device's memory can handle.
Are my files private?
Yes. Processing happens locally in your browser via JavaScript; nothing is transmitted or stored. See our privacy policy for the full picture.
