Split PDF

A single oversized PDF is rarely convenient. You might need to send just one chapter of a manual, separate an invoice from a longer statement, or break a 200-page scan into manageable sections. The Split PDF tool lets you divide a document into multiple files or extract only the specific pages you want, while leaving the original untouched.

This is ideal when a colleague only needs section three of a report, when you want to share a single signed page rather than an entire agreement, or when an upload form imposes a page limit. Instead of forwarding the whole document, you send exactly what is relevant.

Two different jobs share the word 'split'. Extraction pulls out a subset — pages 5 to 12 — and discards the rest, which is what you want when sending someone the one section relevant to them. Division breaks a document into multiple files covering all of it, which is what you want when a 300-page manual needs to become twelve chapter files.

Both work from the same starting point: upload the document, specify the pages, and download the result. Your original file on disk is never modified, so there is no risk in experimenting with ranges until you get the selection right.

Pages are copied rather than re-rendered, so extracted pages retain the exact resolution, text and formatting of the source. Splitting a scan does not degrade it.

The most common splitting error is a mismatch between printed page numbers and actual page positions. A report with a cover, a contents page and two pages of front matter has its printed 'page 1' sitting at position 5 in the file. Ask for pages 1 to 10 and you will get the front matter and only six pages of the content you wanted.

Always count positions in your PDF viewer's page counter rather than the numbers printed on the page. Documents with roman-numeral front matter are the worst offenders here, because both numbering schemes are visibly present and neither matches the file position.

For documents where you will split repeatedly, it is worth noting the offset once — 'printed page N is position N+4' — rather than recalculating each time.

When a file is too large to send, compression is the reflex. Splitting is frequently the better answer.

Compression degrades every page to solve a problem caused by pages the recipient does not need. If someone requires the twelve pages covering their section, sending those twelve at full quality serves them better than sending 200 pages at reduced quality — and it respects their time as well as the attachment limit.

It also matters for confidentiality. A contract often contains commercial terms relevant to one party and not to others. Extracting the relevant schedule is a disclosure decision as much as a file-size one, and sending only what is needed is the more defensible habit.

Because the work happens in your browser rather than on a server, the document is never transmitted anywhere. That matters particularly for splitting, which is disproportionately applied to exactly the documents you would not want to upload: medical letters, legal bundles, financial statements and HR files.

One caution worth stating: extracting pages removes them from view, not from existence. If the pages you left behind contained information that must not reach the recipient, you have solved that by not sending them — but if you need information removed from a page you are sending, that is a redaction task, and covering it with a drawing tool will not do it.
