Why Use an Image Joiner Tool?
Merging images is something we all need to do from time to time. Maybe you want to show a product from different angles in one image for your online store. Or you're comparing two versions of a design and need them side-by-side. Real estate agents often join room photos to create property showcases. Teachers combine educational diagrams. Content creators make comparison images for social media posts.
Instead of opening Photoshop or downloading heavy software, you can do it instantly online. Our image merger handles the technical stuff automatically. You can join 2 photos horizontally to show before-and-after, stack 3 images vertically to show progress, or combine as many as you need. The spacing control lets you add gaps between images or keep them touching. And with proper align mode, all your images match up perfectly regardless of their original sizes.
How to Merge Images Online
Step 1: Upload your images by clicking the upload area or simply drag and drop them in. You can also paste images directly from your clipboard.
Step 2: Drag thumbnails to change their order. The order you arrange them is the order they'll be joined.
Step 3: Choose your direction - horizontal to join photos side by side, or vertical to stack them top to bottom.
Step 4: Pick an arrange mode. "Proper Align" resizes all images to match the smallest one's height/width so everything lines up perfectly. "Free Style" keeps original sizes.
Step 5: Adjust spacing if you want gaps between images. Set it to 0 for no gaps.
Step 6: Select your output format (JPEG, PNG, or WebP) and quality level.
Step 7: Click "Merge Images" to combine them, then download your merged photo.
Common Uses for Image Merging
Before-and-after comparisons are probably the most popular use case. Weight loss progress, home renovations, design iterations, photo editing demonstrations - all look better when you join two photos side by side. Online sellers merge multiple product angles into one image to show more without making customers click through galleries. Real estate listings combine room photos to give better property overviews.
Content creators join memes, reaction images, or screenshot sequences for social media posts. Students combine diagrams or charts for presentations and study materials. Developers merge screenshots when documenting bugs or features. Artists create comparison sheets showing different color variations or style options. Anyone making tutorials joins step-by-step screenshots vertically to show the complete process in one scrollable image.
Frequently Asked Questions
Can I join 2 photos online for free?
Yes! You can join 2, 3, or even 50 photos completely free with no limits. There's no account needed, no watermarks slapped on your images, and no "premium" features locked behind a paywall. Upload your two photos, arrange them how you want, pick horizontal or vertical layout, and merge them. That's it. Download and use anywhere you like.
How do I combine 3 images into one?
Upload all 3 images at once - just select them together or drag them in. They'll appear as thumbnails. Drag to arrange them in the order you want (left to right or top to bottom). Choose horizontal to place them side by side, or vertical to stack them. Click merge and you're done. The tool automatically calculates the final canvas size to fit all three images.
What's the difference between proper align and free style?
"Proper Align" is what you want when images have different sizes but you want them to look uniform. It resizes everything to match the smallest image's dimensions so they all line up perfectly without weird gaps. "Free Style" keeps all images at their original sizes and just places them next to each other as-is. Use free style if your images are already the same size or you specifically want to preserve original dimensions.
Are my photos uploaded to a server?
Nope. Everything happens in your browser. Your images never touch our servers or anyone else's. The merging process uses JavaScript that runs locally on your device. Once you close the browser tab, everything is gone. This means your personal photos, sensitive documents, or private screenshots stay 100% private. We literally can't see them because they never leave your computer.
Can I merge photos horizontally and then add more vertically?
Each merge operation creates one combined image in either horizontal or vertical direction. If you need a complex grid layout (like 2 rows of 3 images each), you'd do it in stages. First merge 3 images horizontally, download that. Then merge another 3 horizontally, download. Finally, upload both merged images and combine them vertically. Takes an extra minute but gets you the layout you need.
What image formats can I merge?
You can upload JPG, JPEG, PNG, and WebP files in any combination. Mix and match different formats in the same merge if you want. For output, choose JPEG for smaller file sizes (good for photos), PNG for lossless quality and transparency support, or WebP for the best balance of quality and file size. The quality slider lets you control compression for JPEG and WebP formats.
Is there a limit on how many images I can merge?
There's no hard limit on quantity, but keep in mind the final merged image size. Merging 50 high-res photos will create a massive file that might be slow to process or download. For most uses, merging 2-10 images works perfectly and keeps file sizes reasonable. If you're joining lots of images, consider using proper align mode and lowering the quality slider a bit to keep the output manageable.
Can I add spacing between joined images?
Yes! The spacing slider lets you add white space between images. Set it to 0 for images that touch edge-to-edge. Or add 10, 20, 50 pixels of gap - whatever looks good for your design. The spacing appears between each pair of images, so if you're merging 3 photos with 20px spacing, you'll get 20px gaps between photo 1 and 2, and between 2 and 3. Great for creating clean looking comparisons or collages.
How do I reorder images before merging?
After uploading your images, you'll see them as thumbnails in the preview area. Just click and drag any thumbnail to move it to a different position. The order left-to-right (or top-to-bottom for vertical) is exactly how they'll appear in the merged result. Drag and drop as many times as you need to get the perfect order, then click merge.
Will merging images reduce quality?
If you choose PNG output format, there's zero quality loss - it's completely lossless. For JPEG and WebP, you control the quality with the slider. Keep it at 90-100% for near-perfect quality. The quality slider is more about file size than visible quality - even 80% looks great for most uses. Proper align mode does resize images to match dimensions, but uses high-quality algorithms so the result still looks sharp.
