Split PDF
Split a PDF into separate files right here — cut it by page ranges like 1-3, 5, 8-10 or every N pages, and get one download per output file. Free, no uploads, no signup.
Separate ranges with commas. A single page is just the number, such as 5; a run of pages is 8-10. One output file is created per range.
Every output file holds this many pages, except the last one, which holds whatever is left.

What is a PDF splitter?
A PDF splitter takes one PDF and produces several smaller PDFs from it. Instead of printing pages to separate files or paying for desktop software, you give the tool the page numbers you want and it writes a new document for each group. This is the same job as cutting a paper report into chapters and stapling each one.
This page offers two ways to split. Split by ranges takes a list such as 1-3, 5, 8-10 and writes one file per range, so you keep control of exactly where the cuts land. Split every N pages takes a single number and writes files of N pages each, in order, which is what you want for scans, statements and batched records.
Everything happens in your browser with the open-source pdf-lib library: the file is read from your disk, the pages are copied as they are, and each output is offered as a separate download. No upload, no server, no account.
How to use this PDF splitter
- Press Choose a PDF file and pick the document you want to cut up. The tool shows the file name, the page count and the file size, and nothing is uploaded.
- Pick a mode. Split by ranges keeps you in control of where the cuts land; Split every N pages cuts at a fixed interval.
- In ranges mode, type the ranges in the text field, for example
1-3, 5, 8-10. In every-N mode, type how many pages each output file should hold. - Press Split PDF. Each output file appears in the list with its name, page count and size.
- Press Download on any file to save just that one, or Download all to save every file in turn.
Worked example
The test file used here is quarterly-report.pdf, a real 10-page PDF that is 2,763 bytes (2.70 KB). It was split with this page, in a browser, and the numbers below are what the tool reported.
Split by ranges, input 1-3, 4, 5-10 — three ranges are read, so three files come out:
quarterly-report-pages-1-3.pdf— 3 pages (pages 1, 2, 3)quarterly-report-pages-4.pdf— 1 page (page 4)quarterly-report-pages-5-10.pdf— 6 pages (pages 5 to 10)
The three outputs contain 3 + 1 + 6 = 10 pages, the whole document, with no page repeated.
Split every 4 pages, same file — 10 ÷ 4 = 2.5, and the file count is rounded up, so 3 files come out: quarterly-report-pages-1-4.pdf (4 pages), quarterly-report-pages-5-8.pdf (4 pages) and quarterly-report-pages-9-10.pdf (2 pages). The last file is short because 10 does not divide evenly by 4.
Wrong input fails safely. Ranges 1-3, 3-5 are rejected because page 3 appears twice, and 1-12 is rejected because a 10-page file has no page 12. In both cases the page shows a message and produces no files.
Who is this PDF splitter for?
- Office and admin work: cut a scanned bundle into one file per invoice, per form or per applicant before filing or emailing, without installing a desktop editor.
- Students and researchers: pull the chapter or the appendix you actually need out of a long paper or lecture pack, and keep the rest of the document untouched.
- Accountants and bookkeepers: split a bank or card statement into months, or separate a client's documents into one file per period, with the page count of every output checked before it is sent.
- Anyone handling confidential files: because the split runs in the browser and nothing is uploaded, private contracts, medical letters and payslips can be split on a work laptop without sending them to a third party.
How ranges and N map to output files
Both tables were computed from the same rules the tool uses: one output file per range, and ceil(pages ÷ N) output files for the every-N mode. ceil means the count is rounded up, so the final file is shorter when the pages do not divide evenly.
| PDF pages | Ranges entered | Output files | Pages in each file | Pages left out |
|---|---|---|---|---|
| 10 | 1-3, 4, 5-10 | 3 | 3, 1, 6 | 0 |
| 10 | 1-3, 5, 8-10 | 3 | 3, 1, 3 | 3 (pages 4, 6, 7) |
| 12 | 1-6, 7-12 | 2 | 6, 6 | 0 |
| 12 | 4, 12 | 2 | 1, 1 | 10 |
| 10 | 1-3, 3-5 | 0 — rejected | – | page 3 is used twice |
| 10 | 1-12 | 0 — rejected | – | there is no page 12 |
Split by ranges: the number of output files is the number of ranges you type, and the pages inside them add up to the pages you listed.
| PDF pages | Pages per file (N) | Output files = ceil(pages ÷ N) | Pages in each file |
|---|---|---|---|
| 10 | 4 | 3 | 4, 4, 2 |
| 12 | 5 | 3 | 5, 5, 2 |
| 12 | 4 | 3 | 4, 4, 4 |
| 12 | 6 | 2 | 6, 6 |
| 10 | 10 | 1 | 10 |
| 10 | 11 | 1 | 10 |
| 10 | 1 | 10 | 1, 1, 1, 1, 1, 1, 1, 1, 1, 1 |
| 365 | 50 | 8 | 50, 50, 50, 50, 50, 50, 50, 15 |
Split every N pages: the file count is always rounded up, so the last file can be smaller than N. Setting N larger than the page count returns the whole document as a single file.
Common use cases
- Splitting a scanned bundle into one file per invoice, receipt or form.
- Cutting a bank or card statement into one file per month before filing it.
- Separating a long report into chapters so each one can be sent on its own.
- Turning lecture slides or a workbook into single-page handouts with N set to 1.
- Pulling the signed pages out of a contract as a small standalone file.
Pro tips
- Check the page count first. The page count shown after loading is the source of truth for ranges — if the reader shows 128 pages, a range of
1-128is the safe full-document entry. - Use N to batch, ranges to be exact. A 1,000-page statement split every 50 pages gives 20 files with no typing; a single chapter needs a range.
- Keep the originals. Output files are new documents; the file on your disk is never modified, so a wrong split costs nothing but a reload.
- Download all in one go. Your browser may ask permission the first time several files are saved at once — allow it for toolcubby.com and the rest of the run is silent.
FAQ
Are my PDFs uploaded to a server?
No. The split runs entirely in your browser using the pdf-lib library, so the file is read from your own disk and the output files are created on your device. Nothing is sent anywhere and no copy of the document is stored.
Is there a page limit?
There is no fixed page limit. The only real constraint is your device's memory, because the whole PDF is held in the browser while it is split. Documents of a few hundred pages are handled comfortably; for very large files, close other tabs first.
Can I split a PDF by bookmark or outline?
No. This tool splits by page ranges or by a fixed number of pages per file, and it does not read the bookmark tree or the chapter structure of a PDF. Open the file in a PDF reader, note the page numbers of each chapter, then enter them here as ranges.
Does splitting a PDF keep the quality, links and form fields?
Yes. pdf-lib copies the original pages as they are, so text stays vector, images keep their original resolution, and internal links and form fields travel with the pages they belong to. Nothing is re-rendered or re-compressed.
Can I split an encrypted or password-protected PDF?
No. A PDF that needs an open password cannot be read by the tool, and the page reports that instead of producing a broken download. Remove the password in a PDF reader, or print the file to a new PDF, then split the unlocked copy.
Why did my file fail to load?
The usual causes are that the file is not really a PDF (a .pdf extension on an image or a text file), that it is password-protected, or that the download was cut short so the file is incomplete. Open it in a PDF reader first; if it opens there, reload this page and try again.
Can I split a PDF into single pages?
Yes. Choose Split every N pages and set N to 1, and every page becomes its own one-page PDF. A 10-page document produces 10 files, each named after the page it contains.
Does the splitter work on mobile?
Yes. It runs in the browser on iOS and Android, and the per-file Download links behave the same way. Processing is slower on a phone than on a desktop, so keep the screen awake for very large files.
Is this PDF splitter free?
Yes. It is free, with no sign-up, no watermark, no page limit and no daily counter. There is no email gate, no account and nothing to install.
Can I merge the split files back together?
Yes. Use the Merge PDF tool to combine them into one document again. That is also a quick way to reorder pages: split the file into single pages, then merge them in the order you want.
What is the difference between splitting a PDF and extracting pages?
Splitting produces several files, one per range or one per group of N pages. Extracting pages produces a single new file that holds only the pages you picked. If you want one smaller PDF, extract; if you want separate documents, split.
