A sheet-fed scanner without a duplexer makes you scan all the fronts, then all the backs β leaving two PDFs that need to be merged page-for-page. Interleaving zips them together in the right order so your double-sided document is whole again, without manual reordering.
Drop both files (fronts first, then backs); the pages are alternated into a single PDF.
The interleaved document is built with pdf-lib on your device. Nothing is uploaded.
Page 1 of the first file, page 1 of the second, page 2 of the first, and so on.
Extra pages from the longer file are appended at the end.
No β interleaving happens entirely in your browser.
