Split PDF
Split a PDF into separate files or extract the pages you need, free and in your browser with nothing uploaded. Split into single pages, typed ranges, chunks of N pages, or odd and even pages, with no loss of quality.
Pages are copied, not re-encoded, so nothing degrades. One document in, as many as you ask for out.
In detail
Split PDF breaks one document into several: one file per page, one file per range you type, fixed chunks of N pages, or two files holding the odd and the even pages. Before you press anything, the Documents list shows exactly what will be written: each output filename, how many pages it holds and which pages those are.
Pages are copied with pdf-lib rather than re-rendered, so there is no quality setting and nothing degrades. To pull out a single page, type its number as a range. To join documents instead, use Merge PDF.
Split PDF at a glance
- Input
- One PDF
- Output
- One PDF, or a ZIP of PDFs named after their pages
- What it does
- Split into single pages
- Split by typed ranges
- Split every N pages
- Split into odd and even pages
- A preview of every output file before saving
- No re-encoding, so no quality loss
- Who it is for
- Anyone sending part of a long document, or breaking a scan into separate files.
- Limits
- Backwards ranges such as 5-2 are rejected as likely typos.
- Past 200 output files, the tool warns that the ZIP will be large.
- A page that links to a page in another part can carry that page into its own file, unseen.
- Privacy
- Runs entirely in your browser: the PDF is never uploaded, and nothing is kept after you close the tab.
How to split a PDF
- Drop a PDF One document at a time. Its name, page count and size appear under Source as soon as it is read.
- Choose how to split it Single pages, ranges, every N pages, or odd and even. Single pages is the default.
- Type the ranges or the chunk size For ranges, write something like 1-3, 7, 9- — each token becomes its own document, and a trailing dash runs to the last page. For every N, set the pages per document; the final one keeps whatever is left over.
- Check the Documents list and the name The list names every file that will be written and the pages inside it. Set the output name if you want something other than the source filename; each document gets its pages appended, as in name-1-3.pdf.
- Split and save Press split and save. A single document downloads on its own; several are packed into a ZIP named after the output prefix.
Split PDF: common questions
Does splitting a PDF lose quality?
No. pdf-lib copies the page objects out of the source into new documents, so text stays text, fonts stay embedded and an image keeps the exact bytes it arrived with. There is no quality or resolution setting in this tool because nothing is ever re-encoded.
What happens if I type a backwards range like 5-2?
It is rejected, with a message suggesting 2-5. A reversed range is far more often a typo than a real request, so the tool asks rather than guessing. (Merge PDF, where reversing a section is a genuine use, does accept them.)
Is there a limit on how many files it will produce?
There is no hard limit, but past 200 documents the tool warns that writing them takes a while and the ZIP will be large. Documents are written one at a time so the page keeps responding. An output that would contain no pages — the even half of a one-page PDF, for instance — is dropped rather than saved as a zero-page file.
