Practical ways to use this tool
Teachers
Alternate paired handouts
Interleave two related sets of equal-sized pages.
Administration
Correct scanner output
Reverse the second stack before combining it.
Features and controls
Assign the two input files
The first file supplies odd positions and the second even positions.
How it works
Choose both PDFs together. The summary identifies which file has each role, and Swap files exchanges them. Each file can be up to 150 MB, with 300 MB combined and up to 600 pages across both inputs. One or three files are rejected.
Correct a reversed scan stack
Reverse odd pages, even pages or both before interleaving.
How it works
Some scanners produce the back sides in reverse order. Enable Reverse even pages when that matches your files. This changes page order only; it does not rotate upside-down scans. Use Rotate PDF separately when page orientation needs correction.
Preview the interleaved sequence
A colored thumbnail sidebar follows the actual output order.
How it works
Browse the left thumbnail sidebar to preview any page in the mixed output. Blue thumbnails belong to file A; peach thumbnails belong to file B. The filenames above the viewer identify the two files, while each thumbnail shows its output position and source page. Colors stay attached to the same source file when you swap or reverse the files.
With odd pages 1, 3, 5 and even pages 2, 4, 6, the result is 1, 2, 3, 4, 5, 6. If the files have different lengths, remaining pages from the longer file are appended. The sidebar updates immediately when the order changes.
Keep the original page appearance
Pages are copied without full-page rasterization.
How it works
Source page sizes, text and artwork are retained. Supported form values are flattened before assembly; document outlines are not merged. Download the combined copy and keep both source files if you may need to rebuild the sequence later.

FAQ
A few useful answers
Know what to expect before you start.
On your deviceWhat happens when the page counts differ?
Pages alternate while both files have pages available. Remaining pages from the longer file are then appended in its chosen order.
Can I mix more than two PDFs here?
No. This workflow is specifically for an odd/even pair. Use Organize PDF or Merge PDF for a larger collection.
