About This Tool

Alternate Merge combines two PDFs by interleaving their pages alternately. This is perfect for combining separately scanned front and back pages into a single document.

Upload two PDFs and the tool will merge them by taking one page from each alternately. You can also reverse the order of one document for back-to-front scanning.

All processing happens in your browser, ensuring your documents remain private.
