How it works
Add two or more PDFs
For example the front pages and the back pages.
Set the order
The first file gives page 1, the second file gives page 2, and so on.
Download
Save the mixed PDF.
Double-sided scans with a single-sided scanner
Scan the front of every sheet into one PDF, then turn the stack over and scan the backs into a second PDF. Add both here to get one document with all pages in order.
If the backs came out last page first, turn on Reverse the second PDF.

Your file is processed inside your browser with the open-source pdf-lib library. It is never uploaded, and nothing is saved after you close the page.
Questions
Are my files uploaded?
No. The tool runs inside your browser, so your files are opened and changed on your own device. They are never sent to us or to anyone else.
What if the PDFs have different page counts?
Pages are taken in turn while each file still has pages. The remaining pages of the longer file are added at the end.
Is it free?
Yes. Free to use, with no sign-up, no watermark and no daily limits.
