Split Every N Pages - Free Online Browser Tool

Automatically chunk a large PDF into smaller files of N pages each.

Some limits are simply a page count: a 300-page dossier has to go out in 50-page pieces, or a 12-page PDF needs four pages per file. This tool does the arithmetic for you — give it a number and it produces evenly sized chunks, with the last file holding the remainder.

This split every n pages utility runs completely inside your web browser. Your document is opened locally and processed on your own device using JavaScript and WebAssembly, so your file is never uploaded to any server. There is no signup, no watermark and no limit on how many documents you can handle.

  • 100% client-side - files never leave your device
  • Instant processing, no upload wait
  • Works on desktop, tablet and mobile
  • Free forever, no account required

How to Use the Split Every N Pages Tool

Four steps, and the whole thing runs locally on your own device.

  1. Load your PDF

    Drop in the file to divide. The page count is read instantly and shown above the control.

  2. Enter the chunk size

    Type how many pages each output file should contain — 10, 25, 50, whatever your limit is. The tool previews how many files that will yield.

  3. Confirm the division

    You will see the exact plan: how many full chunks, and how many pages the final remainder file holds.

  4. Generate and collect

    Press Split Every N to produce all chunks at once, delivered as a single ZIP download.

Frequently Asked Questions

What happens to the leftover pages?

The final file contains the remainder — for a 23-page document split every 10 you get 10, 10 and 3. No page is left behind.

Will I get a warning if I ask for very small chunks?

Yes. Very low values such as 1 are allowed but generate a large number of files, and the tool tells you the file count before you commit.

Can I choose output filenames?

Parts are named with their page range, which keeps them sorted correctly and tells you at a glance what each one covers.

Is there a maximum number of output files?

The practical ceiling is browser memory when packaging a very large number of parts into one archive. Tens of chunks are comfortable; hundreds on a phone may stall.

Does this keep page text selectable?

Yes. Pages are copied, not rasterised, so every part stays fully searchable.
