Interleave PDFs — frequently asked questions
What's the classic use?+
You scanned the fronts of a stack, flipped it, scanned the backs — this merges them back into reading order.
What if the files are different lengths?+
Leftover pages from the longer file are appended at the end.
Do you upload my files to a server?+
No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The AI tools that used to send extracted text to a server are currently disabled.
Is there a file size limit?+
There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
