Joining Options
What is a photo joiner?
A photo joiner connects multiple photos into one joined image. Choose a horizontal layout to place photos side by side, or a vertical layout to stack them from top to bottom.
Use it when you want a straight, linear result: a wide sequence, a tall stack, a before-and-after comparison or a set of photos in order. That is the difference from a collage maker, which arranges photos in a grid.
How to use the photo joiner online
The photo joiner workflow has four steps: add photos, choose a direction, customize the join and download the result.
- Add at least 2 photos. Drag and drop your files into the slots or click to browse. JPG, PNG, GIF and WebP are accepted.
- Choose a direction. Select Horizontal or Vertical. The preview appears as soon as you add the first photo.
- Customize the join. Crop or rotate any photo with its crop button, then adjust size matching, spacing, border width, rounded corners, background color and output size.
- Export and download. Choose PNG, JPEG or WebP, then select Merge & Download.
Nothing needs to be installed. The whole joining workflow runs in your browser.
Photo joiner options and controls
The joining options cover both seamless joins and deliberate gaps.
| Option | Choices | Starts at |
|---|---|---|
| Layout | Horizontal or Vertical | Horizontal |
| Size matching | Keep original sizes, Match largest, Match smallest, Crop to match | Keep original sizes |
| Spacing | 0 to 100 px | 15 px |
| Border width | 0 to 20 px | 0 px |
| Rounded corners | 0 to 50 px | 0 px |
| Output size | Original, Square 1080 × 1080, Portrait 1080 × 1350, Story / Reel 1080 × 1920, Landscape 1920 × 1080 | Original |
| Frame fit | Fit with background, or Fill and crop edges | Fit |
| Per-photo edit | Rotate in 90 degree steps, crop free or at 1:1, 4:5, 9:16, 16:9 | No edit |
| Background | Transparent, white or any color | White |
| Export format | PNG, JPEG or WebP | PNG |
My rule is simple: set the spacing to 0 for a connected join, then increase it when you want a visible gap. For a side-by-side comparison I start with Horizontal. For a tall sequence I start with Vertical.
When should I use a photo joiner?
A photo joiner works well when the photos should read as one connected visual. Common uses include:
- Before-and-after comparisons
- Storytelling sequences
- Panoramic-style horizontal strips
- Social media posts
- Presentations and business slides
- Documentation and tutorial images
For an Instagram Story or Reel cover, pick the Story / Reel output size and the download is exactly 1080 × 1920 px. For a feed post, Square (1080 × 1080) or Portrait (1080 × 1350) matches the common feed shapes. I use Fit when every face must stay in the picture, and Fill when the photos should reach the edges.
Photo joiner versus a collage maker
Choose a photo joiner for a straight connection, and a collage maker for a designed grid. A photo joiner places images in one horizontal or vertical line. A collage maker arranges them in multi-cell layouts and templates.
If you only need a side-by-side sequence, Horizontal Image Merge opens with that direction. If your photos should form one long vertical image, use Vertical Image Merge. Combine Photos Online runs the same tool with its own starting settings. For grid designs, visit the Photo Collage Maker.
Is the photo joiner free and private?
The joining process is free, anonymous and runs in your browser. It requires no account, adds no watermark and does not need any software installed.
Your photos stay on your device while you join and download them. There is one separate, optional action: the Remove Background button on each photo slot uploads that one photo for background removal. If you do not press it, nothing is uploaded. See the Privacy Policy for details.
Try the free photo joiner
I would start with 2 photos, choose the direction that matches your layout and check the preview before changing the spacing or background. You can also use the main Merge Images tool for the same merge with a transparent background to start.

Photo Joiner FAQ
What is a photo joiner?
A photo joiner is an online tool that connects two or more photos into one image. You can place photos side by side horizontally or stack them vertically.
How do I join 2 photos together online?
Add at least 2 photos, choose Horizontal or Vertical, adjust any joining options you need and select Merge & Download. Nothing needs to be installed.
Can I join more than 2 photos at once?
Yes. The joiner starts with 3 photo slots and you can add more. Every photo is connected in the direction you selected, either horizontally or vertically.
Is the photo joiner free online?
Yes. The Photo Joiner is free and anonymous. It needs no signup, adds no watermark and has no paid plan.
Can I join JPG photos with the photo joiner?
Yes. You can add JPG, PNG, GIF and WebP photos and mix them in one join. You can export the joined result as PNG, JPEG or WebP.
Can I join photos for an Instagram Story?
Yes. Under Output size, choose Story / Reel to get an exact 1080 × 1920 px (9:16) image. Fit keeps every photo whole and fills the spare space with your background color. Fill covers the whole frame and trims the edges that do not fit.
What sizes can the joined photo be?
Original size follows your photos. The four fixed sizes are Square 1080 × 1080 (1:1), Portrait 1080 × 1350 (4:5), Story / Reel 1080 × 1920 (9:16) and Landscape 1920 × 1080 (16:9).
Can I crop or rotate one photo before joining?
Yes. Press the crop button on a photo to open the editor. Rotate it in 90 degree steps and drag a crop box, either free or locked to 1:1, 4:5, 9:16 or 16:9. You can reopen the editor later and change the edit, because the original photo is kept.
What if I searched for an old photo joiner, photojoiner or photo jointer?
This page does the same job: add your photos, choose a direction, adjust the spacing and download one joined image, all in your browser.
Is the Photo Joiner an editor or a collage maker?
It is a joiner with editing controls for layout, size matching, spacing, borders, rounded corners, background color, output size and export format, plus crop and rotate for each photo. For multi-cell grid layouts, use the Photo Collage Maker instead.
Does the photo joiner use AI?
No. Joining is plain image drawing in your browser, with no AI step. The only AI step on the page is the optional Remove Background button on each photo slot, and it uploads that one photo only when you press it.
Are my photos uploaded when I join them?
No. Joining happens in your browser, so your photos stay on your device through the download. The exception is the optional Remove Background button: pressing it uploads that one photo for background removal.
