How to Split a Large PDF File

By Contributing Writer

Splitting a large PDF file allows for easier management of a document. If trying to transmit the file via email, splitting up large PDF files would allow you to send the files one at a time without surpassing e-mail size limits. You can use the same techniques for splitting a large PDF file to extract specific pages of a PDF document using the same software--Adobe Acrobat Professional--that you would to simply view PDFs.

Things You'll Need

  • Copy of Adobe Acrobat Professional

Step 1

Open Adobe Acrobat Professional.

Step 2

Navigate to "File," then to "Open" from within the program.

Step 3

Choose the file you wish to open from the file window.

Step 4

With the file open, navigate to "Document," then "Extract Pages." A dialog box will pop up and ask you which pages you'd like to extract.

Step 5

If you'd like to remove the pages entirely from the original PDF, choose the "Delete Pages After Extracting" option from the dialog box. The program will split off the PDF pages into a separate file upon doing this and remove them from the original file.

Step 6

Rename and save the file containing the newly extracted pages.

Tips & Warnings

  • If you don't have Adobe Professional, you can still split a large PDF into smaller files with the help of some third-party software. See the references below for a couple of programs which will allow you to convert larger PDF files to smaller ones.
