How to split a PDF into separate pages or ranges

Short answer: Open the PDF in a split tool, choose a mode, and download the results. Three modes cover almost everything: split into single pages, split by custom ranges such as 1-3,5,8-, or split every N pages into equal chunks. Output arrives as separate PDFs or one ZIP archive.
Splitting is the cheapest edit you can make to a PDF. No page is re-rendered; the tool copies the page objects you asked for into new documents and rebuilds each page tree. Text stays selectable, vectors stay sharp, and images are byte-identical to the originals.
The three modes, and when each is right
| Mode | Output | Use it for |
|---|---|---|
| Single pages | 40 files, one page each | Certificates, tickets, payslips, anything sent to a different person per page |
| Custom ranges | One file per range you type | Chapters, sections, a report split from its appendix |
| Every N pages | ceil(40 ÷ N) equal chunks | Fixed-length units: a 4-page form repeated ten times, or size-limited parts |
| Extract only | One file with the pages you chose | You want a subset, not a set of files |
Split modes and what they produce from a 40-page file.
Splitting step by step
- Open the tool Go to split PDF and drop the file in. It is read in your browser, so a 300 MB file is no slower to load than it is to open in a reader.
- Choose the mode Single pages, custom ranges, or every N pages. If you are not sure, start with custom ranges: it covers the other two.
- Type the ranges Use the syntax below. The preview should show the page count for each output before you commit.
- Name the outputs Most tools use the source filename plus a suffix. Setting a prefix such as
Contract_up front saves renaming a dozen files afterwards. - Download One or two files download individually. More than that usually arrives as a single ZIP.
Split a PDF by pages or ranges without uploading it to a server.
The range syntax
Almost every PDF tool, from Acrobat to command-line utilities to browser tools, accepts the same notation. Pages are 1-indexed, meaning the first page is 1, not 0.
| You type | You get | Notes |
|---|---|---|
5 | Page 5 only | A single page is a valid range |
1-3 | Pages 1, 2 and 3 | Inclusive at both ends |
8- | Pages 8 to 20 | Open-ended means "to the last page" |
-4 | Pages 1 to 4 | Open start means "from the beginning" |
1-3,5,8- | Three separate outputs | Commas separate ranges; each becomes its own file |
1,3,5,7,9 | Five one-page files, or one file of odd pages | Depends on whether the tool is splitting or extracting |
20-15 | Pages 20 down to 15, reversed | Some tools accept a descending range; many reject it |
Range notation, using a 20-page document as the example.
Note: Watch out for documents whose printed page numbers do not match their physical ones. A report with a cover, a blank verso and roman-numbered front matter can have "page 1" printed on physical page 7. Range syntax always means the physical position, so count thumbnails, not the numbers on the paper.
Every N pages, with a real example
A 240-page manual made of twelve chapters, each exactly 20 pages, splits into chapters with a single instruction: every 20 pages. You get 12 files without typing 12 ranges. The mode is only useful when the unit really is fixed, so check two boundaries before you trust it: does file 2 start at the top of chapter 2, and does the last file end where the document does? If chapter 4 runs to 21 pages, every subsequent boundary is wrong.
The other genuinely useful case is size-limited splitting: a 90 MB scan divided into six 15-page parts so each attachment stays under a mail server ceiling. See splitting a large PDF for email for the arithmetic.
Splitting at bookmarks
If the PDF has a proper outline, splitting at top-level bookmarks is far better than counting pages, because the boundaries follow the document's own structure and survive a revision that changes the page count. Not every tool offers it, and it only works when the file actually has bookmarks: a scanned document or a PDF printed from a web page will have none at all.
Why the parts add up to more than the whole
Split a 10 MB PDF into ten files and the total is often 12 to 14 MB. This is expected, not a bug. Fonts, colour profiles and any image used on more than one page are shared resources in the original, stored once. When pages are separated, each output needs its own copy of everything its pages reference. A document with a logo on every page and two embedded font families will duplicate all of it into every part.
If total size matters, compress after splitting rather than before. Compression can also de-duplicate identical objects within each part.
Shrink the split files before you send or archive them.
Other ways to split
- macOS Preview, show thumbnails with ⌥⌘2, select the pages you want and drag them onto the Desktop. macOS creates a new PDF from the selection. Fine for one extraction, tedious for twelve.
- Print to PDF with a page range, works everywhere, but re-renders the document. Links, bookmarks and form fields are lost, and the output can be larger than the input.
- Adobe Acrobat, Organize Pages → Split, with by-page-count, by-file-size and by-bookmark options. The by-file-size mode is genuinely handy and rare elsewhere.
- qpdf, free, offline, scriptable, and the most structurally faithful of the lot.
# Pages 1-3 into their own file
qpdf input.pdf --pages input.pdf 1-3 -- part1.pdf
# Every page as its own file: out-01.pdf, out-02.pdf, ...
qpdf --split-pages input.pdf out.pdf
# Chunks of 20 pages each
qpdf --split-pages=20 manual.pdf chapter.pdfWhat splitting does not do
It does not remove anything hidden. Content covered by a black rectangle, cropped out of view, or sitting in a layer that is switched off travels with the page into the new file. If you are splitting a document to share only part of it with someone, the pages you keep are still carrying everything they carried before. Flatten the output and remove the metadata before sending.
It also does not fix a broken file. A PDF that fails to split usually fails to open properly too. Run it through repair first, then split the repaired copy.
Frequently asked questions
How do I split a PDF into individual pages?
Open the file in a split tool and choose the single pages mode. A 40-page document becomes 40 one-page PDFs, normally delivered as a single ZIP so you are not accepting 40 separate downloads.
What does the range 1-3,5,8- mean?
Three ranges separated by commas: pages 1 to 3, page 5 on its own, and pages 8 to the end of the document. In split mode each range becomes its own file; in extract mode all of them land in one new PDF.
Does splitting a PDF reduce the quality?
No. Pages are copied as objects rather than re-rendered, so text, vectors and images are identical to the source. Quality only changes if you compress the parts afterwards.
Can I split a PDF on a Mac without extra software?
Yes. Open it in Preview, press Option+Command+2 for thumbnails, select the pages you want and drag them to the Desktop. macOS creates a new PDF from the selection. It works well once and gets tedious quickly.
Why are my split files bigger in total than the original?
Fonts, colour profiles and repeated images are stored once in the original but must be copied into each output file. A document with a logo on every page and two embedded fonts will duplicate all of that into every part.
