About Interleave PDF
How Interleaving Works
Interleaving alternates pages from two source documents in sequence. Typical output order is first file page 1, second file page 1, first file page 2, second file page 2, and so on.
Uneven Page Counts
If one source document contains more pages, the remaining pages are appended after alternating pages from both files have been placed.
Output Quality
Pages are copied directly into a new PDF document, preserving layout and compatibility with common PDF readers.
Privacy
This workflow runs in-browser on your device for privacy-focused processing without external upload requirements.
