Frequently asked questions

In what order do the images get stacked?

Images stack top to bottom in the order you selected or dropped them. If you need a specific sequence, add your files in that order, or remove and re-add them until the order is right.

What happens if my images are different widths?

The final canvas is sized to the widest image; narrower images are centered horizontally with white filling the empty space on either side. There's no automatic cropping or scaling to match widths.

Can I merge images side by side instead of stacked?

Not with this tool. It only stacks images vertically into one PNG. For side-by-side layouts, you'd need an image editor, or use a PDF-based tool if a page layout works for your use case.

Do I need an account or a subscription?

Universal PDF requires a Pro subscription. One subscription unlocks every tool on the site, cancel anytime. Merging happens on your device.
