Alternate & Mix
Mix pages from two or more PDFs. Alternate weaves A1, B1, A2, B2. Odd & Even is for duplex scans: the first file is front (odd) pages, the second is back (even) pages. Preview the result, then download. Mixing runs in your browser — nothing is uploaded.

About Alternate & Mix
Mix PDF pages online with this free alternate and mix tool that runs in your browser. Add two or more documents, preview every page, then weave them as A1, B1, A2, B2, or combine a duplex scan: first file for odd (front) pages, second file for even (back) pages, with an option to reverse the backs. Mixing stays on your device. Nothing is uploaded to a server.
People mix PDFs after a scanner saves fronts and backs as two files, when two packs must be interleaved page by page, or when a cover sheet and a form should alternate. Offices rebuild duplex jobs. Students join two scanned halves. Because you see a mixed preview first, the download order matches what you expect.
Add PDFs within the size and page limits, set Alternate or Odd and Even, move files up or down, then download one PDF. Password protected files should be unlocked first with Remove PDF Password. Pair this with Organize PDF to reorder the result, or with PDF Merge if you need whole files joined instead of page by page.
All mixing happens locally, so scans and contracts never leave the browser. Use this free mix PDF tool, odd even PDF combiner, and alternate PDF page mixer whenever two documents should become one interleaved file.
