Questions
What if my images are different sizes?
They are scaled to the same height (side by side) or width (stacked), using the smallest one so nothing is enlarged.
Is there a size limit?
The merged image can be up to 100 megapixels. For very long strips, resize the images first.
Are my images uploaded?
No. Everything runs inside your browser on your own device. Your files are never sent to a server, and you can check: open your browser's developer tools, watch the Network tab, and you will see no upload.
Is it free? Are there limits?
Free, with no sign-up, no watermark and no daily limit. Because the work happens on your device, it costs us nothing to run, so there is nothing to ration. You can add up to 50 images at a time.
