Quick answer: Splitting a PDF separates one document into smaller files: extract the pages you want, remove the ones you do not, or divide it into chunks. The tool shows exactly which files you will get before it makes anything, and pages are copied, not re-rendered, so quality is untouched.
The six modes, and when to use each
| Mode | What you get | Use it when |
|---|---|---|
| Extract pages | One PDF, or one per page | You want a chapter, a form or a few pages |
| Remove pages | One PDF | It is quicker to say what goes than what stays |
| Every page | ZIP, one file per page | Every page is its own document |
| Every N pages | ZIP of fixed chunks | A portal caps uploads at a page count |
| Split at points | ZIP, one file per section | You know where each document in a scan ends |
| Equal parts | ZIP of N files | Sharing a long report across several people |
Remove pages is the one people miss
Most splitters only extract, so dropping page 7 from 30 means typing 1-6,8-30 yourself. Remove mode inverts it: type 7 or tap page 7 and everything else is kept, with the final page count shown before you commit.
See the output before you make it
Every mode lists the files it will produce, with page counts, as you change settings, so an off-by-one range is caught before you run the job. Pages render as thumbnails, and the odd and even buttons split a double-sided scan’s fronts from its backs in one click.
How the browser-based splitter works
It uses pdf-lib to copy the pages you choose into new files and JSZip to bundle multi-file output into one download, all in your browser. Text, fonts, vectors and images carry across untouched, and your original file is never modified. The limit is device memory: a few hundred pages is fine on a desktop.
When you need to split a PDF
- Pull out one chapter from a long manual or report.
- Break up a scanned batch into one file per invoice or contract.
- Drop pages before sending: blank sheets, notes or confidential appendices.
- Meet an upload limit by chunking, then compress if size is still a problem.
- Separate a double-sided scan with odd and even.
Privacy
Your PDF is read and divided entirely in your browser. It is not uploaded, not stored and no account is needed. Site analytics are covered in our privacy policy; the document stays on your machine.
Frequently asked questions
Is the Split PDF tool free?
Yes, with no signup, watermark or trial. The only limit is your device’s memory.
Are my files uploaded?
No. The file is read and divided inside your browser tab and never transmitted.
Can I extract specific pages?
Yes. Type a range such as 1-3, 5, 8-10, or tap page thumbnails. The two stay in sync.
How do I delete pages instead of keeping them?
Switch to Remove pages and name the pages to drop. Everything else is kept.
Can I split into files of a fixed length?
Yes. Every N pages makes fixed-size chunks; Equal parts divides into a set number of files.
What does splitting at points do?
It cuts after the pages you name. 3, 7, 12 on a 20-page file gives pages 1–3, 4–7, 8–12 and 13–20.
Does splitting reduce quality?
No. Pages are copied, not re-rendered, and your source file is never modified.
Can I split a password-protected PDF?
Not until the password is removed. The tool tells you when you add a locked file.

Accuracy note: Each mode is described from what the tool actually produces, and the preview lets you check it yourself. Open the split files before sharing a document that matters.
