Merge PDF

Append PDFs in a deliberate file order and inspect the resulting page sequence. Processing runs in your browser.

Two PDFs contain three labeled pages each. The output should contain six pages in the file order or alternating order you choose.

A practical guide

Control the sequence at each document boundary.

  1. Select the source PDFs.
  2. Order files by the sequence required in the final document.
  3. Merge and verify the first and last page contributed by each file.

Try this example

Append a three-page methods note before a five-page data table PDF. The result contains eight pages, with the table beginning at position 4.

Before

  • Methods: 3 pages
  • Tables: 5 pages

After · one PDF

  • 1-3 Methods
  • 4-8 Tables
Appended file order determines the resulting page positions. Illustrative example.

Before you start: Append preserves each file's internal page sequence. This does not merge page contents; page sizes can differ between source PDFs.

Separate the combined PDF into groups
