Merge Images
Turn several photos into one. Great for comparisons, before-and-after shots and Instagram collages.
🔒 Your photos are never uploaded. They are merged right here on this device.
How to use it
- Before and after — put 2 photos "Side by side". Ideal for fitness progress, home makeovers or photo edits.
- Long screenshots — join chat or web page screenshots into one image with "Stack vertically".
- Instagram collage — arrange 4 or 9 photos as a 4:5 "Grid collage".
If the merged file is large, use Compress Image; to add text, try the Photo Editor. More tools are in Image Tools.
Frequently asked questions
Are my photos uploaded to a server?
No. Once you pick your photos, they are combined only on this device, inside your browser. Nothing is sent over the internet, so it is safe for personal photos, and nothing is kept after you close the page.
Can I combine photos of different sizes?
Yes. Side by side, the heights are matched automatically; stacked vertically, the widths are matched. For a grid collage, choose a cell ratio and pick "Fill cells" to crop each photo to fill its cell, or "Show whole photo" to keep the entire photo with some empty space.
Does it work with iPhone photos (HEIC)?
Yes. HEIC photos are converted to JPG automatically before merging. You can add up to 30 photos at a time.
What if the merged image is too large?
So that phone browsers can handle it, the result is automatically scaled down to about 16 megapixels at most (long side up to 10,000 pixels). To make the file smaller still, run the saved image through Compress Image.
