Split PDF

  • Click Page > Split > the popup opens.

    enter the number

    By number of pages: You just need to enter the number. If you enter 100, then every 100 pages will become a new document. If the number of pages cannot be evenly distributed, the last document will be less than 100 pages.

    By file size: If you enter 4, the PDF will become several new 4.00 MB PDF documents.

    By top-level bookmarks: After you create bookmarks, you can split the document according to the bookmarks. For example, if you place a bookmark on page 99 and page 150, then pages 1-99, 100-150, and pages after 151 will be divided into 3 PDF documents.

  • After the split is completed, the new document will be automatically saved to the local folder, and the new documents can be found by Open the folder.
