Frequently asked questions
Why not just merge them?
Merging puts all the fronts first and all the backs after. Mixing alternates them, which is what a double-sided document needs.
The files have different lengths.
Pages alternate while both files last, then the rest of the longer file is appended.
Where is my file processed?
On your own machine. The tool is code that runs inside your browser tab, so the document is never sent to us and never sits on a server waiting to be cleaned up.
