Frequently asked questions
Are my images uploaded to a server?
No. Every operation runs entirely inside your browser using your device's own processor. Your files never leave your computer, so the tool works even with the page disconnected from the internet after loading.
Can I combine images vertically and horizontally?
Yes. Choose 'Vertical' to stack images top to bottom, 'Horizontal' to line them up side by side, or 'Grid' to tile them in rows and columns.
What if my images are different sizes?
For vertical layouts every image is scaled to a common width, and for horizontal layouts to a common height, so the seams line up cleanly. Grid mode centres each image inside an equal cell.
Can I add space between the images?
Yes, use the gap slider to add padding between tiles. The gap is filled with the background color you choose.
Which output format should I pick?
PNG is lossless and keeps transparency; JPG and WebP produce smaller files, which is handy when stitching many photos into one large image.
