Built for speed, privacy and reliability — on any device.
Pages from two PDFs are alternated: 1A, 1B, 2A, 2B, 3A, 3B…
Scan front and back separately, then mix them into the correct order.
PDFs with different page counts work — extra pages go at the end.
Mixing runs locally — your PDFs never reach a server.
No account, no limits, no watermarks.
The most common use is recombining double-sided scans. Scan all front sides first, then all back sides, then mix them alternately to get the correct reading order.
Extra pages from the longer PDF are appended at the end after interleaving.
