Step by step

How To Alternate & Mix PDF Pages

Two or more documents, read in turn — set how each file behaves, press Mix, and the pages interleave themselves.

  1. 1

    Upload your PDFs

    Add two or more documents — pages will alternate between them. Sort A–Z or Z–A if the order matters; every file is deleted after 2 hours.

  2. 2

    Set how each file reads

    For every row: keep Regular Order or switch to Reverse Order, and set how many pages the document reads before the mix moves on — “Switch document after reading 2 pages”. Each row also carries preview and remove.

    The Alternate & Mix screen on desktop: three document rows with Regular / Reverse Order choices and a switch-after-N-pages box, the Add more files rail with A-Z / Z-A sorting, and the Mix PDF files button
  3. 3

    Mix and download

    Press Mix PDF files and the alternating document opens ready to download, share or print.

  • Alternates between documents

    Reads from each file in turn — ideal for interleaving scans, statements or two-language versions.

  • Any cycle length

    Switch after N pages: take one page apiece, or read a run from each document before moving on.

  • Reverse any document

    Flip a file's page order before it joins the mix — the others stay as they are.

  • Sort in one click

    Order the list A–Z or Z–A without dragging anything around.

  • Add files as you go

    More files can join at any time — from this computer, the clouds or a web address.

  • Private by default

    No account, no watermark — and every file is automatically deleted after 2 hours.

Alternate & Mix — frequently asked questions

What is Alternate & Mix for?

The classic two-pass scanning trick: scan all fronts into one PDF and all backs into another, then let the tool interleave them back into reading order. Each file can have its own step and reversed order.

Is Alternate & Mix free?

Yes — Alternate & Mix is free right here in your browser, with no watermark and no sign-up. Every tool on the site works the same way.

Do I need an account to use Alternate & Mix?

No. Accounts are optional — they keep your credits, API keys and settings together. The tools work signed-out.

What happens to my file?

Every upload is stored under an unguessable id and deleted automatically after 2 hours. Nothing is listed, shared or emailed anywhere.

Can I run Alternate & Mix from the API?

Yes — every tool has a REST endpoint. An API call for this tool costs 5 credits per task; browser use stays free. See the Plans & pricing page for plans and the API page for the endpoint list.
