Duplex Scanning Tip:

This tool perfectly merges separate scans of odd and even pages.
Note: If your even pages were scanned in reverse order (common with some auto-feeders), please use our 'Reverse Page Order' tool on that file before interleaving them here.

Merge Front and Back Scans Seamlessly: The Intelligence of "Duplex Interleave"

Struggling with a single-sided scanner for double-sided documents? Simply scan your front pile and back pile separately. Our smart interleaving engine merges them into a perfectly sequenced 1, 2, 3, 4 PDF in seconds.

Case 01. Professional Results with Basic Hardware

An office administrator needed to digitize hundreds of double-sided contracts but only had a basic single-sided ADF scanner. Manually flipping each page was taking hours.

By using **Max-PDF’s Duplex-Interleave**, she scanned all the fronts as one file and all the backs as another. The engine automatically zipped them together—placing page 2 after page 1, page 4 after page 3, and so on. A task that usually required an expensive duplex scanner was solved for free in seconds.

Case 02. Handling Reverse-Scanned Back Pages

A student noticed that after scanning the front of his book, scanning the back pile resulted in a "reverse order" file (e.g., page 100, 98, 96...). Manually reordering 50 pages was a nightmare.

He used the **"Reverse Second File"** option in the Duplex Interleave tool. The system flipped the back-page sequence automatically and then interleaved it with the front pages. The result was a flawless 1-100 PDF with zero manual effort.
