Alternate and mix PDF pages online

Highlights
Page by page
One page is taken from each file in turn: A1, B1, A2, B2…
Reverse the second file
If the back sides were scanned by flipping the whole stack, they are in reverse order; this option puts them right.
Local processing
The files are processed in your browser and are not uploaded to a server.
FAQ
How is this different from merging?
Merging puts files one after another. Alternate & mix takes a page from each file in turn and interleaves them.
When do I need reverse order?
If you scan the fronts, flip the whole stack and scan the backs, the back pages run from last to first. Take the second file in reverse order in that case.
