A PDF, or portable document format file, is an ideal way to transfer information while still keeping it on lock down. PDFs are readable, but not editable without specialty software. After creating a document in almost any kind of software, converting that file to PDF ensures someone can open it even if he doesn't have that software. When PDFs get bloated, or contain too much information to handle at once, splitting the file may be an ideal way to trim file size, reach target readers and control who sees what information. Splitting PDFs into multiple PDFs requires just a bit of manipulation of the original document.
Double-click the PDF you want to split. PDFs are symbolized by a square icon showing a small preview of the PDF's first page and the red square Adobe icon symbol.
Click the "Pages" link on the left side panel of the PDF window if the page preview is not showing. The page preview shows a listing of each page of the PDF in vertical format.
Press and hold down the "Ctrl" key on the keyboard. Click once on each page of the PDF to strip out or remove. These are pages you do not want in the new PDF. Press the "Delete" key on the keyboard.
Click the "File" menu. Click "Save a Copy." Rename the PDF, such as "NewPDF1." Select a place to save the new PDF and click the "Save" button. Click the "File" menu and select "Close."
Reopen the original PDF, the one with all the pages. Repeat the "Pages" link deletion process to strip out pages for the next version of the PDF. When saving, rename the file with a new file name, such as "NewPDF2," and increments from there on.
The Adobe Reader software is required to open and split PDFs. If you don't have Reader installed, you'll see a question mark or other type of icon noting that your computer doesn't recognize the PDF. Reader is free and available from the Adobe company.
