How to Split a PDF on a Mac

Published September 7, 2026

macOS is unusually well equipped here. Unlike Windows, which ships no PDF page tools at all, a Mac gives you three separate ways to split a document without installing anything: Preview, the print dialog, and a Finder Quick Action. Most people know about one of them, pick the wrong one for the job, and end up either flattening a form or quietly overwriting the original file.

Here is what each method really does, when to reach for it, and the safest option when the document is something you cannot afford to damage.

First, decide which split you actually need

Nearly every “split this PDF” job is one of two tasks, and the right method differs:

• Extract a range — pull pages 12–15 out of a 40-page report and keep them as one new file. This is what you want for sending a chapter, submitting one section, or returning a signature page.
• Break it apart — turn a 12-page file into twelve one-page PDFs. This is for batch scans where several unrelated documents ended up in one file.

Preview handles the first well and the second badly. The Quick Action does the opposite. Knowing which you need before you start saves a lot of dragging.

Method 1 — drag pages out of Preview

This is the one worth learning, because it is fast and it does not modify the source document.

1. Open the PDF in Preview (double-clicking usually does it).
2. Show the sidebar: View → Thumbnails, or Cmd + Option + 2.
3. Click the first page you want, then Shift-click the last to select a run, or Cmd-click to pick scattered pages.
4. Drag the selection out of the sidebar and drop it onto the Desktop or a Finder window.

macOS writes the dragged pages out as a new PDF, keeping their order, and the file you opened is left exactly as it was. Two details catch people out: the new file is named after the original with the page numbers appended, so rename it straight away; and if you drag a single page it still arrives as a proper one-page PDF, not an image.

Method 2 — delete pages and export (careful with this one)

The obvious approach is to open the file, select the pages you do not want in the thumbnail sidebar, press Delete, and save. It works, and it is also where most Mac PDF disasters come from.

Preview saves back to the file you opened. macOS auto-saves document changes, so by the time you close the window the original may already be a shorter document, and Time Machine or a version history is your only route back. If you take this path:

1. Use File → Duplicate (Cmd + Shift + S) before deleting anything, and work on the copy.
2. Delete the unwanted pages in the thumbnail sidebar.
3. Use File → Export as PDF and give the result a new name in a folder you will find again.

Method 1 avoids all of this, which is why it is the better habit.

Method 3 — the print dialog

Every Mac app can write a PDF from its print sheet, and the print sheet has a page-range field. Press Cmd + P, set Pages to a custom range such as 12 to 15, then open the PDF pop-up menu at the bottom left and choose Save as PDF.

It is quick and it works from any app, not just Preview. The catch is that printing re-renders the pages instead of copying them. Filled form fields become flat text, clickable links stop working, and digital signatures are invalidated because the signed bytes no longer exist. For a page someone only needs to read, that is fine. For a form or a signed agreement, use a method that copies pages rather than reprinting them.

Method 4 — the Finder Quick Action

Recent macOS versions include a Split PDF Quick Action. Turn it on in System Settings → General → Login Items & Extensions → Finder (older releases: System Preferences → Extensions → Finder), then right-click any PDF in Finder and pick Quick Actions → Split PDF. macOS drops one PDF per page into a folder beside the original.

This is the fastest way to explode a batch scan into individual pages, and it is genuinely one click. Its limitation is that it is all-or-nothing: there is no way to say “pages 4 to 9 only.” If you find yourself wanting selective splitting on a schedule, an Automator workflow can do it, but for a one-off job it is far more effort than typing a range into a tool.

Which method for which job

Method 5 — split in the browser

The browser route is worth knowing even on a Mac, for three reasons: it never edits the source file, it handles both range extraction and full page-by-page splitting in the same place, and it behaves the same on the office PC when you are not at your own machine.

1. Open the Split PDF tool in Safari or Chrome and drop your PDF onto the box. The page count appears.
2. For a slice, set from and to — for example 12 to 15 — and click Extract range. Use the same number twice to pull a single page.
3. For a full break-up, click Save each page separately and every page downloads as its own PDF.
4. Files land in your Downloads folder. Rename them before they pile up.

Because the work happens inside the page on your own Mac, there is no upload and no progress bar, and it keeps working if the Wi-Fi drops after the page has loaded.

Mac-specific things that trip people up

• Page numbers are physical, not printed. Preview's toolbar shows “14 of 40” — that first number is the one to use, not the number printed in the footer.
• Quick Look is not Preview. Pressing Space in Finder gives you a viewer with no thumbnail sidebar. Open the file properly before you go looking for the split controls.
• Locked PDFs refuse to be edited. If Preview will not let you delete or drag pages, the document has an owner password. You will need the password — no legitimate tool works around it.
• Scanned PDFs split fine but stay unsearchable. Splitting does not add text recognition; a scan of a page is still an image afterwards.
• Mixed orientations look odd once separated. A landscape page extracted from a portrait report keeps its rotation — fix it with a PDF rotator if it should match.

Is it private?

Preview and Quick Actions are local by definition, which is one of their real advantages. The risk arrives when people reach for a random web splitter for a contract or a bank statement, because most of them upload the whole document to a server and rely on a deletion timer. Toolyard's Split PDF tool runs entirely in your browser — the file is never uploaded, there is no sign-up, no watermark and no daily limit. If you later need to put pieces back together, the PDF Merger works the same way.
