About Alternate & Mix PDF
Alternate & Mix takes pages in turn from each PDF you add: A1, B1, A2, B2 and so on. It is ideal when a double-sided stack was scanned as two separate files. You can reverse either file first, and everything stays on your device.

Frequently asked questions
How do I combine front and back scans?
Add the fronts file first and the backs file second. If the backs were scanned from the bottom of the stack, tick Reverse for that file, then press Alternate & mix.
What if the files have different page counts?
The extra pages from the longer file are added at the end.
Are my files uploaded anywhere?
No. This tool runs in your browser, so your file stays on your device and is never sent to a server.
