Merge Images FreeNo signup · 100% local · Free
Combine several images into a single picture: stack vertically for chat screenshots, product details or step-by-step guides, or place them side by side for comparisons, panorama segments and timelines. Images are arranged in the order you add them.
When sizes differ, pick start, center or end alignment, and set a pixel gap to add breathing room between frames. Output supports PNG, JPG and WebP with a quality control.

FAQ
What if the images have different sizes?
Images are arranged using the alignment you chose (start / center / end) and the canvas takes the maximum extent in each direction. Nothing is stretched or cropped — every image keeps its original proportions.
Can I reorder the images?
The current version keeps the order in which you added them. To change it, click "Clear" and add them again in the desired order.
The merged image is too big — what can I do?
Export as JPG or WebP and lower the quality to shrink the file. You can also run the source images through the compressor first and then stitch them.
How many images can I merge?
There is no hard cap; it depends on your device memory. More images, or larger ones, mean longer processing time.
Are my images uploaded?
No. Stitching happens locally in your browser — no image is ever uploaded to a server.
