Merge PDF

PDF merge probably is the most used PDFsam module and lets you merge PDF documents together.

Page ranges

Input PDF documents can be merged completely or partially. A page selection can be easily set in the form of comma separated intervals (Ex. 1-10, 14, 25-) letting you specify what pages you want to merge for every input PDF document.


With PDFsam you will be able to decide what to do with the PDF documents outline (bookmarks). You can merge them to the resulting document, discard them to keep the merge document smaller or create a new one with one entry for every merged PDF document.


And what to do with AcroForms when they are found in the input PDFs? You can discard them but also merge them into a new form or even merge them renaming fields with name clashes.

PDF Split

The Split module let's you split PDF documents at predefined or specified page numbers.

Split at predefined pages

The selected PDF document can be split after every page, generating a new document for every page in the original document, or after every ever or odd page.

Split specifying pages

Specify the page numbers where you want to break your document. You can even tell PDFsam to split the PDF every n pages!

PDF Split by bookmarks

Select the outline (bookmarks) level you want to split at and your document will be divided at every page pointed by the bookmarks at the selected level.

PDF Split by size

Split PDF documents into smaller files of a given size (roughly).


The PDF mix module lets you merge two PDF documents taking pages alternately in straight or revers order. The perfect solution if you have two documents containing even and odd pages respectively and you want to rebuild the original document.

Rotate PDF

Select the PDF documents you want to rotate and apply a rotation of 90, 180 or 270 degrees to their pages.
