How to use Split PDF
- 1Drop in a PDF — the page count is read from the file
- 2Choose one file per page, or a single range
- 3For a range, type it as 5-12
- 4Run it and watch each output document being built
- 5Download the pieces, numbered in order
What Split PDF does
Splitting is the only page operation that produces more files than it consumes. Everything else here — deleting, extracting, reordering — takes one document and hands back one document. Splitting takes one and hands back many, which changes what you get at the end and how you work with it.
The pages themselves are moved rather than rebuilt. Each output document is created empty and the relevant pages are copied into it complete with their fonts, images and vector content, so a scanned page in piece four is byte-for-byte the scan it was in the original. Nothing is re-rendered at any point.
When to use it
- A scanner batch that is really several documents
- Feeding a stack of unrelated paperwork through one scanner produces a single PDF. Splitting per page, or by range, gives back the separate documents.
- Distributing individual certificates
- A generated PDF holding one certificate, payslip or invoice per page becomes a folder of individual files, each ready to send to a different person.
- Getting under an upload limit
- When a portal caps file size and the document is genuinely long, splitting into parts is often accepted where one compressed file is not.
- Working on one section at a time
- Pulling a chapter out as its own document makes it easier to annotate, print or hand to someone without giving them the whole book.
Split PDF settings explained
- One file per page
- Produces as many documents as the source has pages, each holding a single page. Progress is reported per document, so a long split shows how far along it is rather than appearing to hang.
- Single range
- Produces one document from the pages you name — 5-12, or a comma-separated mix like 2, 5-8. This overlaps with extracting pages; the difference is mostly which mental model you arrived with.
- Output naming
- Files are named freetools-split-1.pdf, freetools-split-2.pdf and so on, numbered in output order so the sequence survives even after your browser reorders the downloads.
- Page labels
- Each result is labelled with what it contains — the page number in per-page mode, or the page count for a range — so you can identify a piece without opening it.
Split or extract
| Split (per page) | Split (range) | Extract pages | |
|---|---|---|---|
| Files produced | One per page | One | One |
| You specify | Nothing | A range | Any list of pages |
| Can reorder | No | No | Yes |
| Typical use | Separating a batch | Taking one section | Building a custom subset |
Limits and what to expect
- Per-page mode on a long document produces a lot of files — a 200-page PDF becomes 200 downloads.
- Only one range at a time in range mode; several separate sections mean running it more than once.
- Bookmarks, links and form fields are not carried into the split documents.
- Each piece keeps its pages' original dimensions, so a mixed-size source produces mixed-size outputs.
- Documents requiring a password to open cannot be read; permission-restricted ones are fine.
Troubleshooting
- The browser blocked the downloads
- Splitting a long document per page triggers many downloads at once, which browsers treat as suspicious. Allow multiple downloads for the site when prompted, or split by range instead to produce a single file.
- The pieces are in the wrong order in my downloads folder
- Downloads finish out of order, but the filenames are numbered in output sequence. Sort by name rather than by date and the original order is restored.
- The parts add up to more than the original
- Each document repeats the structural overhead the original held once — the fonts a page uses have to be embedded in every file that contains it. On a heavily formatted document this is noticeable.
- I want several separate sections at once
- Range mode takes one selection per run. Either run it several times, or use extract pages, which accepts a list of ranges and produces a single document from all of them.
Your files and your privacy
The document is read into the browser tab and each output is assembled there before being offered for download. No file is uploaded and nothing is stored on a server. Because splitting is often the step before sending different pieces to different people, keeping the whole source on your own device is the point.

FAQ
How do I split a PDF into separate pages?
Choose one file per page and run it. Each page becomes its own document, named freetools-split-1.pdf onwards in order. Your browser may ask permission for multiple downloads, since a long document produces a lot of files.
Can I split a PDF in half?
Use range mode twice: once for the first half, once for the second. Range mode takes a single selection per run, so two halves means two runs.
What is the difference between splitting and extracting?
Splitting can produce many files — one per page — while extracting always produces one. In range mode the two overlap almost completely; extraction is the more flexible of the pair, because it accepts several ranges at once and honours the order you type them in.
Does splitting reduce quality?
No. Pages are copied as complete objects into the new documents, with their fonts and images intact. Nothing is re-rendered or re-compressed.
Why do the split files add up to more than the original?
Structural overhead is repeated. A font embedded once in the source has to be embedded in every piece whose pages use it, so a document split into fifty parts carries that cost fifty times.
Is my document uploaded?
No. Reading the source and building every output happen inside your browser on your own device, and the tool works with the network disconnected.
