Put front and back scans in page order
Drop the fronts PDF and the backs PDF. Pages are mixed one by one: front 1, back 1, front 2, back 2. Turn on reverse backs if the scanner captured the reverse side from the last page backward. Both files stay on your device.

Questions
How do I combine front and back scans?
Put the odd or front sides in the first box and the even or back sides in the second. Tap Combine. Download the mixed PDF.
When should I reverse the back pages?
Use it when you flipped the stack and scanned the backs from the last sheet to the first. The last back is then paired with the first front.
What if the two PDFs have different page counts?
Pairs are made until the shorter file runs out. Extra pages from the longer file are added at the end, in their own order.
Does this upload my scans?
No. Mixing runs in your browser. Nothing is sent to a server.
Can I reorder after mixing?
Yes. Download the result, then open Organize pages if a sheet is still out of order.
