Merge Images
Use Merge Images, review the result, and keep the original until the output is checked.
How to use Merge Images
- Add every image you want combined, then use Add More Images to extend the list.
- Choose Horizontal or Vertical for the strip, and Alignment to decide how mismatched heights sit against each other.
- Set Spacing (px) and Background Color for the gutter between pictures.
- Reorder or fix individual files with the rotate and flip controls per tile, then run the merge.
What Merge Images actually does to your file
Files of different sizes are placed as they are, so a tall phone photo next to a wide screenshot gives you a tall strip with visible padding. The merge re-encodes once, so pick PNG when the combined image contains text or line art.
Merge Images FAQ
What does Merge Images do?
Merge multiple images into one online for free. Combine photos horizontally or vertically with custom spacing, preview instantly, then download in seconds.
Which files work with Merge Images?
This category commonly supports JPG, PNG, WEBP, GIF, BMP, and SVG. Use the accepted file types shown in the uploader, because support varies by browser and by the engine behind each tool.
Can I change the order of the files before merging?
Reorder the selected files in the list before you run the merge. The output follows the order shown on the page, not the order in which you picked them.
Will my original file be changed?
No. The work is done on a copy in this tab by the canvas and the codecs built into your browser, and the result arrives as a separate download, so your original is still there if you need it.
How is my file processed?
It is not uploaded. The processing is done locally by the canvas and the codecs built into your browser, so the practical ceiling is your device's memory and the limit shown beside the uploader - no queue, no account, no copy on a server.
Is the Merge Images free?
Yes. The Merge Images is free with no trial limit, subscription, or watermark on downloads. You can use it for personal and commercial projects without creating an account.
