Split PDF

Split a PDF free in your browser: extract pages from a PDF, cut it every N pages, or into custom ranges. No upload, no signup, no watermark.

Your PDF never leaves your device. It is processed locally in your browser, not uploaded to any server.

How to verify: open DevTools → Network, then use the tool. No request carries your file.

How to split a PDF

  1. Drop a PDF onto the page, or click to choose one.
  2. Choose a mode: Extract pages (click thumbnails or type 1-3, 5), Split every N pages, or Custom ranges.
  3. Check the list of files that will be created.
  4. Click Download. Several files are saved one after another.

Which split mode should I use?

  • Extract pages pulls chosen pages out into one new PDF, such as a single chapter or the signed page of a contract. Tick "each page as its own PDF" to get one file per page instead.
  • Split every N pages suits scans of many similar documents, like a stack of two-page forms scanned in one go.
  • Custom ranges gives you full control: 1-4, 5-9, 10- creates three PDFs with exactly those pages.

Private by design, and the limits

The PDF is read and split inside your browser with the open-source pdf-lib library, so it is never uploaded. To confirm, open DevTools → Network while you split: no request carries your file. Pages are copied without re-compression, so quality is unchanged. Password-protected PDFs need the password removed first, and since there is no ZIP step, a split into many files triggers many downloads; most browsers ask once whether to allow that.

To delete or rearrange pages instead of splitting them out, use Organize PDF; to put parts back together, use Merge PDF. More tools are in the PDF tools collection.

Frequently Asked Questions

How do I extract pages from a PDF?↓

Open the PDF, keep the Extract pages mode, and click the page thumbnails you want or type a range such as 2-4, 7. Click Download PDF and the selected pages are saved as a new PDF. The original file is not changed.

How do I split a PDF into multiple files?↓

Choose Split every N pages to cut the document into equal parts, or Custom ranges and type ranges like 1-3, 4-8, 9- to get one PDF per range. Click Download and each file is saved one after another.

Is my PDF uploaded when I split it?↓

No. The PDF is split inside your browser and never leaves your device. You can confirm this by opening DevTools, switching to the Network tab and splitting a file: no request carries your document.

Why did only one file download when I split into several?↓

Browsers often block a site from saving several files in a row until you allow it. Look for a prompt or an icon in the address bar, choose to allow multiple downloads for this site, and click Download again.

Does splitting a PDF reduce its quality?↓

No. Pages are copied exactly as they are, with their text, fonts and images, without re-compression. Text stays selectable and searchable, and no watermark is added.

Can I split a password-protected PDF?↓

Not directly. Encrypted PDFs are detected and you'll see a message asking you to remove the password first. Open the file in the app that created it, save an unprotected copy, and split that copy.
