About This Tool
Interleave pages from two PDF files in an alternating pattern with our free online tool. Combine front and back scans, merge odd and even pages, or weave any two documents together page-by-page, creating output compatible with Adobe Acrobat and all PDF viewers.
Upload two PDF files and our tool alternates pages: page 1 from file A, page 1 from file B, page 2 from A, page 2 from B, and so on. Essential for reconstructing double-sided documents scanned as separate front and back files, or combining any two documents that need page-by-page interleaving.
All PDF interleaving happens entirely in your web browser. Your documents never upload to remote servers, making this the safest way to merge confidential scans, legal documents, financial records, and sensitive two-sided originals. No registration required, no file size restrictions.
Perfect for combining single-sided scanner output into double-sided documents, merging translated documents with originals for comparison, or creating flashcard-style layouts. Works with all standard PDF files including scanned images, Adobe Acrobat documents, and files from any PDF-creating application.
