Frequently asked questions
Is it free to use?
Yes, the app is free to download and use.
Where are combined images stored?
They're stored only on your device and are never sent to or kept on my servers.
Where can I pick images from?
You can select images from your device's camera roll (photo library).
Is there a limit on how many images I can combine?
There is no fixed limit. Combining a large number of very large images can take a while, depending on how much memory the device has.
Does combining reduce the resolution?
No, the original resolution is kept. If text looks blurry, exporting as PNG keeps it crisp.

Yes, it can build a PDF with the selected images stacked vertically. That feature is Premium only.
Can I choose the arrangement?
Vertical, horizontal or a grid, and you can reorder the images.
