Split PDF

Split PDF by number of pages#

This operation splits a PDF into multiple smaller documents. Simply use the page count to specify the maximum number of pages of each output file.

Split PDF by page ranges#

As an alternative to creating smaller PDFs with a set number of pages, you can split PDFs into multiple smaller documents by specifying page ranges where each page range corresponds to a single output file.

Split PDF into number of files#

As an alternative to creating smaller PDFs by specifying a set number of pages or a page range, you can split PDFs by file count. In this case, the operation creates the specified number of files with each containing an identical number of pages (if possible).
