Automatically rotate the second file by 180° and interleave it with the first. Fix upside-down scanning errors in a single step.
What is 'Rotate Interleave'?
When merging two PDFs, this tool
automatically flips every page of the second file 180 degrees
(upside down) and then interleaves them with the first file. It’s the perfect fix for scanners that capture the back side of pages in reverse orientation.
Is it safe for sensitive scans?
Completely.
Max-PDF processes everything

Your files are never uploaded to our servers, ensuring your data never leaves your device. This provides total privacy for legal, financial, or personal documents.
Why do I need to rotate pages?
Many Automatic Document Feeder (ADF) scanners generate the second side of a duplex scan
upside down
due to the way paper is flipped inside the machine. This tool eliminates the need for manual rotation of every individual page.
What is the correct upload order?
File 1 (Normal)
: The front pages that are already correctly oriented.
File 2 (Upside-down)
: The back pages that need to be rotated 180°.
The tool intelligently applies rotation only to the second file before merging.
Will rotation blur my document?
No. We use
Lossless Metadata Correction.
We don't re-render or re-compress the images; we simply change the rotation flag in the PDF structure. Your original resolution, OCR layers, and searchable text remain perfectly intact.
What if the page counts are different?
The tool interleaves as many pages as possible. If one file is longer than the other, the
remaining pages will be appended
to the end of the document (retaining their rotation status), ensuring no data is lost.
The Smartest Way to Align Your Scans
Manually rotating and reordering hundreds of pages is a productivity killer. Max-PDF automates the technical correction of hardware scanning errors.
