Combine images into one without uploading
Stitch several photos or screenshots into a single picture β top to bottom, side by side, or in a grid.
π Your images never leave your deviceTo bundle pictures into one document instead, Image to PDF is a better fit. To make the joined image smaller, use Compress image; to trim it, use Crop image.
Why stitch screenshots on your own device
The things people most often stitch together are exactly the things they should not be uploading: a chat thread captured in five screenshots, the front and back of an ID card, a long receipt or form photographed in parts. Sent separately they arrive out of order and have to be opened one by one; joined, they read as one page. This page reads each image in your browser, draws them onto a single canvas and saves that canvas. The preview is the output, so what you see is exactly what you get β and none of it ever reaches a server.
Common uses
Long conversations β join partial screenshots vertically into one tall image.
Before and after β place two photos side by side so the difference is obvious.
Listings and posts β put several angles of an item into one grid image.
Document uploads β combine the front and back of a card into a single file.
Frequently asked questions
Are my images uploaded anywhere?
No. Everything happens inside your browser and nothing is sent anywhere. The page keeps working with the internet switched off, so it is safe for chat screenshots and ID documents.
Can I change the order?
Yes. Use the β β buttons next to each image to move it and β to remove it; the preview updates immediately. Choosing more images adds them to the end of the list.
What if the images are different sizes?
By default everything is shrunk to match the smallest image, so nothing is enlarged and nothing gets blurry. "Enlarge to the largest image" scales small ones up, which can soften them slightly. "Keep original sizes" leaves every image untouched and fills the leftover space with the background colour.
How many images can I combine?
There is no fixed limit. If the result would be too large for the browser to draw (around 100 megapixels), the whole image is scaled down to fit and a note appears above the preview saying so.
The result is extremely tall.
Stacking many images vertically does that. Switch the layout to a grid with 2β3 images per row to get a shape that fits on a screen.
What happens to transparent PNGs?
Saved as JPG, transparent areas are filled with the background colour. PNG output also fills gaps and leftover space with that colour.
