Split PDF by Page Number 2026 — Free Online

Break a PDF at a fixed page interval. Set the number of pages each output should hold and the document is divided into equal chunks — a 30-page file split every 10 gives you three 10-page PDFs. The whole thing runs in this tab, so the document is never uploaded.

Splitting at a fixed interval

You give one number: how many pages each output file should contain. The document is then cut at every multiple of it, in order, until there is nothing left. Thirty pages split every ten produce three files; thirty-two produce four, the last holding the two pages that did not make a full chunk.

This is the right operation when a document has a regular structure — a booklet printed four pages to a signature, a report where each section runs to a fixed length, a scanned batch where every form is the same number of sheets. It takes one number instead of a list of page numbers.

Every page ends up in one of the outputs. Nothing is discarded, which is the difference between this and extraction.

  • 30 pages every 10 — three files
  • 32 pages every 10 — four files, the last holding two pages
  • Set the interval to 1 to get one file per page

When a list of pages suits better

A fixed interval assumes the document divides evenly. Plenty do not — a batch scan where invoices ran to three, then five, then two pages has no single number that fits.

For that, the page range option takes a list such as 1-3, 4-8, 9-10 and cuts exactly there, and selecting pages by thumbnail works when you want particular sheets rather than a run. All three modes sit on this page; the interval is simply the quickest when the structure is regular.

What survives the split

Pages are copied rather than re-rendered, so images keep their resolution, text stays selectable and fonts stay embedded. Splitting a file repeatedly does not degrade it.

Annotations and form fields attached to a page travel with that page. Bookmarks pointing at a page that ended up in a different output file have nowhere to point and are dropped, which is worth knowing before splitting a long report that relied on its outline.

Frequently Asked Questions

How many files will I get?

The page count divided by the interval, rounded up. Thirty pages every ten gives three files; thirty-two gives four, and the last one holds the remaining two pages.

What happens to the leftover pages?

They become the final file. A chunk that does not fill the interval is still written out — nothing is discarded.

How is this different from splitting every page?

Splitting every page is this with the interval set to 1. Any larger number keeps that many pages together in each output.

What if my document does not divide evenly into sections?

Use the page range option instead — it takes a list such as 1-3, 4-8, 9-10 and cuts exactly there. A fixed interval only helps when the structure is regular.

Is my PDF uploaded to split it?

No. The file is read and rewritten inside this browser tab and never leaves your device, which is why there is no size limit and no queue.
