One side normal, the other side reversed? Don't rescan. Max-PDF magically restores the correct page order for scrambled duplex scans.

What is 'Zigzag Scan Recovery'?

It's a specialized tool for duplex scans where front pages are in order (1, 3, 5...) but back pages are captured in reverse (...6, 4, 2) . This tool flips the second file and weaves it correctly into the first one.

Is it safe for sensitive documents?

100% Secure. Max-PDF operates on a local-only processing engine. Your files never reach our servers and stay within your browser's memory. This ensures total confidentiality for legal, financial, or personal records.

In what order should I upload files?

1. Normal File : Upload the file with front pages (1, 3, 5...) first.
2. Reversed File : Upload the file with back pages (...6, 4, 2) second.
The tool will automatically detect and reverse only the second file before interleaving.

Will reordering pages reduce quality?

No. We use Lossless Object Reordering. We don't re-scan or re-compress the pages. We simply rearrange the internal PDF pointers, preserving original resolution, OCR text, and formatting perfectly.

What if the files have different page counts?

The tool intelligently interleaves pages as far as possible. If one file is shorter than the other, the remaining pages are appended in their respective (or reversed) order, ensuring no data loss.

How is this different from a normal merge?

A normal merge just joins files end-to-end. This tool performs a complex 'Reverse + Interleave' workflow specifically designed to rescue failed or unconventional duplex scanning results.
