Sometimes you do not need an entire PDF. You may only need a few pages for email, uploading, sharing, or creating a smaller document.
Splitting a PDF lets you turn one large document into several smaller files while keeping the original document available as a backup.
Upload or open the PDF, select the pages or page ranges you want to separate, create the new files, and check each result before deleting the original.
When Should You Split a PDF?
Splitting a PDF is useful when only part of a document needs to be shared or stored separately.
Method 1: Split a PDF Online With Adobe Acrobat
Adobe Acrobat's online Split PDF tool lets you mark where a document should be divided into separate PDF files.
After uploading the PDF, you select the divider positions between page thumbnails and then save the resulting files.
Decide the page ranges before you start. For example, if you want pages 1 to 3, 4 to 7, and 8 to 10 as separate files, knowing the ranges first makes the process much faster.
Different Ways to Split a PDF
Depending on the Acrobat version you use, PDFs can be divided in several different ways.
Method 2: Extract PDF Pages on Mac With Preview
Mac Preview does not require a separate PDF splitting tool if you only want to create a new PDF from selected pages.
You can display the page thumbnails, select the pages you need, and drag them to the desktop to create a new PDF.
2. Select View and then Thumbnails.
3. Select the page thumbnails you want.
4. Drag the selected thumbnails to your desktop.
5. Open the new PDF and check the pages.
Keep the original PDF until you have checked that the new file contains every page you need.
Check the Split Files
Before sharing the new PDFs, open each one and confirm that the document was divided correctly.
Split or Extract: What Is the Difference?
These two terms are related, but they are not exactly the same.
What If the New PDF Is Still Too Large?
Splitting a PDF reduces the number of pages in each file, but it does not necessarily compress the images or other data inside those pages.
If the split PDF is still too large, use lighter compression afterward. See our guide: How to Compress a PDF Without Losing Quality.
Need to Put the PDFs Back Together?
If you later need to combine the files again, you can merge them into one document.
See our guide: How to Merge PDF Files Into One PDF.
