Open the Organize Pages tool using the shortcut in the right pane or from the Tools center, accessed at the top left.
In the Open dialog box, select the Bodea.pdf sample file or other PDF file you want to split into two or more documents.
In the secondary toolbar that opens, use the Split by drop-down menu to specify if you want to split the PDF file by number of pages, maximum file size, or top-level bookmarks. In the Bodea.pdf sample file, set the number of pages to 6. If you want to create a PDF of a specific range of pages, learn more about extracting pages from a PDF.
Click Output Options to specify a target folder for the split PDF files and set file labeling preferences. For the Bodea.pdf sample file, use the default options, which save copies of the new split PDF files in the same folder where the original file is saved and adds Part 1 and Part 2 labels to the end of each new file name. Click OK to proceed.
Click the Split button, and then click OK when Acrobat provides confirmation that the PDF document has been split into two new files. Acrobat automatically saves the split files to the target folder.

You can also extract pages with Adobe Acrobat DC or merge files, including Microsoft Word documents, Excel spreadsheets, and PowerPoint presentations.
