What is Photo Merger?
Photo Merger stitches several images into one — stacked vertically for long screenshots or placed side by side in a row. It's a free way to merge photos online in your browser: add two or more images, choose a direction, and download the combined picture as a single PNG.
Key features
- Vertical stacking for long screenshots and photo strips
- Horizontal layout for left-to-right rows
- Add any number of images; thumbnails show the order
- Outputs one PNG, filling size gaps with white
How to merge multiple photos into one
Photo Merger stacks several images into a single picture — vertically for a long strip, or horizontally for a row. It keeps every image at its full original size and simply places them end to end, which makes it the right tool when you want a faithful, no-fuss combination rather than a hand-arranged layout.
Using it
- Add images (two or more). Add more whenever you like; the thumbnails below show the order they'll be combined in, which is the order you added them.
- Choose a direction:
- Vertical stacks images top to bottom — ideal for long screenshots, chat logs, receipts, or a conversation captured across several screens.
- Horizontal places them left to right — good for a comparison row or a filmstrip.
- Merge & download. You get a single PNG named
merged.png.
How the canvas is sized
The output dimensions come straight from your images. For a vertical merge, the width is the width of your widest image and the height is the sum of all the heights. For a horizontal merge, the width is the sum of the widths and the height matches the tallest image.
Because images are aligned to the top-left of each slot, any image that's narrower (vertical) or shorter (horizontal) than the largest one leaves empty space, and that space is filled white. If your screenshots were all captured at the same width — as phone screenshots usually are — the vertical result lines up perfectly with no white at all. Mixed sizes are where the white padding shows up.
Merger vs. Combine Photos Side by Side
These two tools look similar but serve different needs:
- Photo Merger (this one) does a straight, full-size stack in a fixed direction. No dragging, no scaling — just add and merge. It shines on uniform screenshots.
- Combine 2 Photos Side by Side is an editable canvas where you drag, resize, and match dimensions. Reach for that when your images are different sizes and you want them scaled to match, or when you want to position them freely.
If your vertical strip is coming out with white edges because one screenshot is wider than the others, the Combine tool's Match widths preset is the fix.
Good to know
- The output is always a PNG, so it's lossless — there's no quality slider to worry about.
- There's no reordering control here; set the order by adding images in the sequence you want them.
- Everything runs in your browser on a canvas; none of the source photos are uploaded.
- A dozen full-resolution photos in a row produces a very large canvas. If you plan to upload the strip somewhere with a size limit, run the result through Resize or Compress afterward.
Frequently asked questions
- Why is there white space on one side of my merged image?
- Images are aligned to the top-left, so any image narrower (vertical merge) or shorter (horizontal merge) than the largest leaves a gap that's filled white. Screenshots of the same width stack with no white; mixed sizes show padding.
- Can I reorder the images before merging?
- There's no drag-to-reorder here — images combine in the order you add them, shown by the thumbnail row. If the order is wrong, reset and re-add them in the sequence you want.
- How is this different from Combine Photos Side by Side?
- Photo Merger stacks images at their full native size with no editing; Combine is a drag-and-resize canvas. Use Combine, and its Match widths preset, when images are different sizes and you want them scaled to match before merging.
- Does merging shrink or compress the images?
- No. Each image is placed at its original resolution, so a vertical merge's height equals the sum of every image's height. The output is a lossless PNG — run it through Compress or Resize afterward if it's too big to upload.
- Which direction is best for a long screenshot?
- Vertical — it stacks captures top to bottom, matching how you scrolled. It's ideal for chat logs, articles, and receipts split across several screenshots of the same width.

Stitching the images together is a canvas operation performed locally; none of the source photos are uploaded.
