About Image Combiner
Image Combiner is a small, free tool that does one thing well: it takes several pictures and joins them into a single image, in your browser, without uploading anything anywhere.
Why it exists
Joining a few photos into one image is a five-second idea that somehow always turns into a chore. Desktop editors are overkill for it. Most online tools want an account, push watermarks, or quietly upload your photos to a server. Phone apps bury the feature under subscriptions.
This site is the shortcut: open the page, drop in your images, pick a layout, download the result. No account, no watermark, no upload. It is the tool we wished existed, so we built it.
How it works, technically
Everything happens locally in your browser using the HTML5 Canvas. When you add photos, they are read directly from your device into the page's memory, arranged and rendered on your own hardware, and saved straight back to your device. There is no processing server. Your images never travel over the network, which is also why the tool feels instant even with large photos.
That design is a genuine privacy guarantee rather than a policy promise: private photos, medical documents, screenshots of conversations, ID scans - none of it leaves your machine, because there is nothing for it to be sent to.
Why it is free
The site is supported by advertising, which covers hosting and development. That model keeps the tool itself unrestricted: every feature works for everyone, there is no premium tier, no export limit, and no watermark. We would rather have a simple tool that many people use than a paywall in front of a five-second task.
What it can do
- Combine images side by side, stacked vertically, in a grid, or arranged freely on a canvas
- Rotate, flip, duplicate, reorder, and resize individual images
- Control spacing, borders, rounded corners, background color, and transparency
- Handle mixed image sizes with four sizing strategies
- Export as JPG, PNG, or WebP at full resolution
- Undo and redo, keyboard shortcuts, and full touch support on phones
If you are new to the tool, the guides walk through the most common uses: before/after comparisons, Instagram collages, and stitching screenshots.
