To split a PDF into separate files, you choose where the cuts go (specific page ranges, every few pages, or after every single page) and save each part as its own PDF. You can do this with a dedicated splitter, with your browser's "Save as PDF" print option, or with Preview on a Mac. Which one you pick depends mostly on how many pieces you need.
This guide explains the three main ways to split, walks through native options on each platform, and shows how to split a file in one pass with a private in-browser tool.
Three ways to divide a PDF
Before you open any tool, decide what kind of split you need. Nearly every real-world task falls into one of these patterns.
By custom page ranges
You know exactly where each section starts and ends. For example, a scanned bundle containing an invoice on pages 1 to 2, a delivery note on page 3 and a contract on pages 4 to 9. You would split into ranges "1-2", "3" and "4-9".
Every N pages
The document has a regular structure. A batch scan of twenty two-page forms should become twenty files of two pages each. A class set of four-page quizzes should become one file per student.
One file per page
Every page stands alone, such as a stack of scanned receipts or a set of certificates. Each page becomes its own PDF.
Split vs. extract vs. delete
These terms are easy to mix up:
- Splitting produces several output files that together cover the pages you specify.
- Extracting produces one new file containing just the pages you pick. Use Extract pages when you only need, say, pages 5 and 12 in a single document.
- Deleting produces one file with the unwanted pages removed. Delete pages is the right choice when you want to keep almost everything.
Choosing the right operation up front saves you from splitting a file into ten parts only to merge three of them back together.
How to split a PDF in your browser
Our free Split PDF tool handles all three patterns in one place. It runs inside your browser, so the document is processed on your own device and never uploaded.
- Open Split PDF and drop your file onto the page.
- Choose a mode:
- Each page creates one PDF per page. This is the default.
- Every N pages creates chunks of a fixed size. Enter the number of pages per file, for example 2 for two-page forms. If the total does not divide evenly, the last file simply contains the remaining pages.
- Custom ranges lets you describe the parts yourself. Type ranges separated by commas, such as "1-2, 3, 4-9". Each range becomes its own file.
- Run the split.
- Download the resulting files.
Writing good ranges
A few habits make range-based splitting painless:
- Page numbers refer to the physical position in the file, starting at 1, not to the numbers printed on the pages. A report whose first printed number is "iii" still starts at page 1.
- Open the PDF in any viewer first and jot down the page where each section begins. The viewer's page counter shows physical positions.
- Ranges do not need to cover every page. Anything you leave out is simply not included in the output, which doubles as a quick way to drop cover sheets.
Native ways to split a PDF
You do not always need a dedicated tool, especially for a quick one-off.
Using Chrome or Edge on any computer
Chromium-based browsers can "print" a subset of pages to a new PDF:
- Open the PDF in the browser.
- Press Ctrl+P (Windows) or Command+P (Mac).
- Set the destination to Save as PDF.
- Under Pages, choose Custom and enter a range, for example "4-9".
- Click Save and name the file.
Repeat for each part. This is fine for two or three pieces, but it gets tedious fast. Also be aware that "printing" regenerates the document: links, bookmarks, form fields and some accessibility information may be lost, and it will fail on PDFs whose permissions block printing.
Using Preview on a Mac
Preview offers two approaches.
Drag thumbnails out:
- Open the PDF and choose View > Thumbnails.
- Select one or more thumbnails.
- Drag them to the desktop or a Finder window. macOS creates a new PDF containing those pages.
Print to PDF:
- Choose File > Print.
- Set a page range.
- Use the PDF menu in the lower-left corner and choose Save as PDF.
The drag method is surprisingly quick for pulling out single pages. For many sections, it becomes repetitive.
Using Windows
Windows has no built-in PDF splitter. The usual workaround is Microsoft Print to PDF: open the file in a browser or PDF viewer, print, choose Microsoft Print to PDF as the printer, and enter a page range. It shares the same limitations as browser printing, and you repeat it for every part.
Using Adobe Reader
The free Adobe Reader focuses on viewing, commenting, and filling forms. Splitting and page organization are features of the paid Acrobat product, although you can still use Reader's print dialog with Microsoft Print to PDF or macOS's Save as PDF as described above.
Practical splitting scenarios
Separating a batch scan
Office scanners often produce one long PDF from a stack of paper. If each document has the same length, use Every N pages. If lengths vary, flip through once, note the starting pages, and use Custom ranges. Check for blank separator sheets and leave them out of your ranges.
Meeting upload size limits
Portals for job applications, court filings or insurance claims often cap the size of each file. Splitting a large PDF into sections is one fix. Before splitting, try Compress PDF; a single compressed file is usually easier for the recipient than several fragments.
Sending only what is needed
Sharing an entire 80-page contract when someone needs one schedule exposes more information than necessary. Split or extract just the relevant pages. If the remaining pages still contain sensitive details, use Redact PDF to remove them properly.
Distributing individual pages
Certificates, tickets, and payslips generated as one large PDF are a classic case for Each page. After splitting, rename files to something meaningful before sending them out.
Pitfalls and how to avoid them
- Confusing printed and physical page numbers. Always use the viewer's page counter when writing ranges.
- Losing interactivity. Print-to-PDF workarounds can drop links and form fields. A dedicated splitter copies pages instead of reprinting them.
- Splitting protected PDFs. Files with an open password must be opened with the password first. If you are entitled to the file, Unlock PDF can save an unlocked copy.
- Forgetting shared resources. Each split file carries the fonts and images its pages need, so the parts together can be slightly larger than the original. That is normal.
- Messy output names. When you split into many parts, rename them promptly. "Invoice-March.pdf" is far more useful than a numbered file a month later.
Checking your split files
A quick review prevents embarrassing mistakes, especially when the parts go to different people:
- Open the first and last file and confirm they start and end on the pages you expect.
- Count the files. With Every N pages, the number of outputs should equal the total page count divided by N, rounded up.
- Spot-check orientation. A sideways page in the original stays sideways in its part. Fix it with Rotate PDF before sending.
- Look for stray blank pages that belong to the previous or next section, and trim them with Delete pages if needed.
Putting pages back together
Splitting is not a one-way door. If you split too finely, recombine the pieces with Merge PDF. To fine-tune page order within a single file, Organize PDF is the better tool.
Key takeaways
- Decide first whether you need ranges, fixed-size chunks, or one file per page. For a single subset, extract instead of split.
- Chrome, Edge, Preview and Microsoft Print to PDF can split by printing page ranges, but they rebuild the document and can drop links and forms.
- Our in-browser Split PDF tool offers all three split modes in one pass and keeps your file on your device.
- Use physical page positions when typing ranges, and review the output before sharing.
