Frequently asked questions

What is collating good for?

Interleaving front/back scans, alternating chapters from separate PDFs, or building a duplex-ready document.

Do the PDFs need the same page count?

No. When one file runs out, remaining pages from the others continue in order.

Is it lossless?

Yes. Pages are copied from the source PDFs without re-encoding.
