Alternate & Mix PDF Pages
Combine PDFs by taking pages from each in turn. The classic use: you scanned the fronts of a stack, then the backs, and need them merged in the right order. Reverse any file with one tick.

Why use it
What this free tool does
Alternating pages
1 from A, 1 from B, 2 from A, 2 from B, and so on.
Reverse any file
Back sides usually scan last page first.
Several at a time
Take 2 or more pages from each file per turn.
More than two files
Mix three or more PDFs in rotation.
Uneven lengths
When one file runs out, the others carry on.
Lossless
Pages are copied exactly as they are.
Fronts and backs, back together
Scanners without a duplex feeder make you scan a stack twice: once for the fronts, then turned over for the backs. The backs come out in reverse order. Add the fronts file, then the backs file with Reverse ticked, and the pages come out 1, 2, 3, 4 in the right order.
Forms and links are kept with their pages.
Tip: Some pages blank after mixing? Run the result through Remove Blank Pages.
