Split PDF
Built in your browser · nothing is uploaded
Splitting builds new documents out of the pages you name. Three ways cover almost everything: one file per page, one file per range, or a single file containing just the pages you picked, which is the one to reach for when you need a chapter out of a long report.
How to split a PDF
The range box is deliberately forgiving, and knowing exactly how forgiving saves a puzzled minute. Commas, semicolons and spaces all separate groups. A bare number is that page alone. 4- runs from page four to the end. A pair written backwards, 9-4, is read as 4-9 rather than rejected. Anything outside the document is clamped instead of refused, so asking for 1-50 of a twelve-page file gives you the twelve pages. Numbers are the pages as you see them, counting from one.
The one thing it will not do is guess. A group it cannot parse is skipped in silence rather than flagged, and the commonest cause is a dash that is not a hyphen: 4–9 pasted out of a word processor, where autocorrect has quietly replaced the hyphen with an en dash, matches nothing and vanishes from the selection. If a range you typed did not appear in the output, retype the dash. When every group fails the panel says so rather than producing an empty file.
In the one-file mode the order you type in is the order you get, and duplicates are dropped. Typing 5, 1-3 produces a four-page document whose pages run 5, 1, 2, 3, which makes the range box a crude reordering tool as well as a selector. Each output keeps the original page content untouched, so text stays selectable and the resolution is unchanged. Splitting five hundred pages is fine, and anything producing more than one file arrives as a ZIP.
What people use it for
- Pulling one chapter out of a long report
- Separating a scanned batch into one file per document
- Sending a single page without the rest of the contract
Questions
Choose One file and type that page number. You get a single-page PDF with the original page inside it.
Page four to the last page. It saves counting when you want everything from a point onwards.
Commas, semicolons and spaces as separators, a backwards pair like 9-4 read as 4-9, and any number beyond the end clamped to the last page rather than rejected.
A group that cannot be read is skipped without complaint, and the usual culprit is an en dash rather than a hyphen, which is what a word processor produces when it autocorrects 4-9. Retype the dash.
In the one-file mode, yes: pages come out in the order you asked for them and duplicates are dropped, so 5, 1-3 gives a document running 5, 1, 2, 3.
Yes. Scanned pages are images inside a PDF and are copied exactly as they are, with no re-compression.
Roughly proportionally, though shared resources such as embedded fonts are copied into each output, so the parts can add up to more than the whole.
No. The parser here has no decryption in it, and encryption is ignored rather than removed, so an encrypted file splits into documents of the right page count whose pages will not render — with no error to warn you. That holds for a file that needs a password to open and for one that merely forbids printing or editing. Take the protection off first.
No. It is read and rebuilt entirely in this page.
