Upload two images, choose horizontal or vertical merge direction, adjust optional gap and background settings, then download the merged PNG, JPG, or WebP file. The tool is designed for merging two images into one static result.
Free Image Merger to Merge Images Online
Use this image merger to merge images when you need two photos, screenshots, or graphics combined into one file. Upload two images, choose a side-by-side or vertical layout, adjust spacing and background color if needed, then export the result as PNG, JPG, or WebP. The tool is built for a focused combine images workflow: two images in, one merged image out. It runs in your browser with Canvas processing, so your selected image files are not uploaded to a server for merging.
What This Image Merger Does
This page combines exactly two images into one static image. It is useful when you want to compare two pictures, place screenshots together, join product photos, or create a simple before-and-after image without opening a design app.
| Input | Layout options | Output |
|---|---|---|
| Two browser-readable image files | Horizontal merge, side by side | PNG, JPG, or WebP |
| Two photos, screenshots, or graphics | Vertical merge, top to bottom | One downloaded merged image |
| Mixed source sizes | Automatic scaling to matching height or width | Optional JPG/WebP quality setting |
| PNG or JPEG images | Gap size and background color | Static image result |
For a horizontal merge, the images are scaled to the same height and placed left to right. For a vertical merge, the images are scaled to the same width and stacked top to bottom. You can also swap the two images before merging.
This is not a PDF tool, AI image combiner, collage template editor, panorama stitcher, or batch image merger. If you need to combine images into a PDF document, use Image to PDF instead.
How to Merge Images Online
1
Upload two images
Choose the first and second image from your device, or drag image files into the upload slots. The upload area accepts common browser-readable image files, including formats such as JPG, PNG, WebP, GIF, and AVIF when your browser can decode them.
2
Choose horizontal or vertical merge
Select horizontal when you want to merge images side by side. Select vertical when you want to combine images from top to bottom. Use the swap button if the left/right or top/bottom order needs to change.
3
Adjust spacing and background
Open the advanced settings if you want a visible gap between the two images. Gap options include 0px, 5px, 10px, 20px, and 30px. The background color fills the gap area and also fills transparent source pixels during export.
4
Pick PNG, JPG, or WebP
PNG is a practical default for screenshots and graphics. JPG is useful for photo-style output and broad compatibility. WebP can be useful for web workflows that accept it. The quality setting applies to JPG and WebP output.
5
Merge and download
Click the merge button to create one combined image. The result downloads as a static file with a filename that indicates the layout direction.
Merge Images Side by Side or Vertically
Merge images side by side
Side-by-side merging places the first image on the left and the second image on the right. This layout is best for before-and-after comparisons, product comparisons, two screenshots from the same workflow, and images that should be viewed together in a wide format.
When the two source files have different dimensions, the tool scales them to the same height. That keeps the final result aligned instead of leaving one image shorter than the other.
Combine images vertically
Vertical merging places the first image above the second image. This layout works well for long screenshots, step-by-step examples, mobile screen comparisons, receipts, chat screenshots, and other content that reads from top to bottom.
When image sizes differ, the tool scales both images to the same width before stacking them. This creates a clean column-style output.
Output Settings for PNG, JPG, and WebP
The output format changes how the merged file behaves after download. Choose the format based on where the combined image will be used next.
| Output format | Best for | Notes |
|---|---|---|
| PNG | Screenshots, UI captures, text-heavy graphics | Uses the selected background color behind transparent areas |
| JPG | Photos, email attachments, broad compatibility | Smaller files are possible with lower quality |
| WebP | Website images and modern web workflows | Quality setting can reduce file size |
If your source image has transparent pixels, the exported canvas still uses the selected background color. Choose white for a clean default, or set another background color when the space between images should match a design.
If you need to resize the finished merged image after export, use Image Resizer as a second step.
Common Uses for Combining Images
Before-and-after comparisons
Use the horizontal layout to put two photos side by side. This works for edits, repairs, design changes, makeup results, room updates, and other visual comparisons where the viewer needs to see both states at once.
Screenshots and tutorials
Use vertical layout to combine two screenshots into a single image for a support message, tutorial, documentation note, or social post. A small gap can make the two sections easier to read.
Product and listing images
A photo combiner is useful when you want to show two angles, two colors, or two detail shots in one image. Keep the background consistent so the combined image looks intentional.
Social and message sharing
Merge pictures into one file when an app or message thread handles one image more easily than two separate attachments. Export as JPG for broad compatibility or WebP when the destination supports it.
Privacy, Browser Processing, and Limits
The merge step runs in the browser using a temporary canvas. Your selected files are read locally for preview and merging, and the downloaded result is generated from that browser canvas.
There are still a few limits to know before writing copy or planning a workflow:
Two images only
The current page has two upload slots and does not merge a batch of many images
Static output
Animated GIF input should be treated as a still-image workflow
No PDF export
The output choices are PNG, JPG, and WebP
No AI generation
The tool does not blend faces, invent missing detail, or generate a new scene
Browser decoding matters
Some formats may fail if the browser cannot load them
For more advanced editing after the merge, use a dedicated editor. This page stays focused on a fast merge 2 images task.
Image Merger FAQ
Use the two upload slots for your first and second image. Choose side-by-side if you want them left and right, or vertical if you want one above the other. Click merge to create one combined image.
Upload both pictures and select the horizontal merge direction. The first picture appears on the left and the second picture appears on the right. Use the swap button if you want to reverse the order.
Yes. Select the vertical direction to stack two images from top to bottom. The tool scales both images to the same width before merging them, which helps the final image look aligned.
Open the tool in your iPhone browser, choose two photos from your device, select horizontal or vertical layout, then merge and download. The workflow is browser-based; it does not require installing a separate app from this page. Always check the downloaded file before deleting or replacing originals.
Yes, as long as your browser can load the files. You can merge PNG images, JPEG images, WebP images, and other browser-readable image files. The export format can be PNG, JPG, or WebP.
Yes. Open advanced settings and choose a gap size: 0px, 5px, 10px, 20px, or 30px. You can also choose the background color that fills the gap.
No. The merge action runs in your browser using Canvas. The selected files are used locally for preview and export, and the merged image is generated for download from the browser.
No. The current tool supports two images at a time. If you need to combine many images, process them in pairs or use a dedicated multi-image collage or batch tool.
No. This image merger exports PNG, JPG, or WebP. To turn images into a PDF document, use Image to PDF.
