Merge PDF files into one

Combine invoices, scans or chapters into one PDF. You see every page before you download, and nothing is uploaded.

How it works

  1. Choose your PDFs

    Drop them into the window or pick them with the button. Every file becomes its own block, and every page gets a label such as A1.

  2. Put them in order

    Drag a block onto another block to merge them, or choose All documents and then Merge all into one PDF. Drag single pages to where they belong.

  3. Download

    You get one PDF with the name you choose. If you have several documents, you get them together in a ZIP.

Useful for

  • A month of invoices in one file for your accountant.
  • A scanned contract with its appendices behind it.
  • Front and back sides of a scan interleaved in the right order.
