How to Split a PDF and Extract Only the Pages You Need
How to extract a page range while keeping the original intact, and why the number printed on the page is so rarely the number the tool wants.

The page number on the page is not the page number
This is the single most common reason an extraction comes out wrong. A report with a cover, a contents page and two pages of front matter has printed page one sitting at position five. Ask for pages one to three and you get the cover.
Use the position in the file, which is what your PDF viewer shows in its page counter, not the number printed in the corner of the paper. When they disagree, the viewer is right about what the tool will do.
Extract into a new file, always
Splitting should never modify the document you started with, and here it does not: the pages you ask for are copied into a new file and the original is left alone on disk. That matters because extraction is where people discover they took the wrong range, and the fix is simply to do it again rather than to find a backup.
Send the pages, not the document
Most extraction is really about not oversharing. The four pages someone needs from a forty-page contract are the four pages they should receive; the rest is context they have no reason to read and you have no reason to hand over.
It is also the most effective way to get under an attachment size limit. Dropping thirty-six pages beats any amount of compression, and unlike compression it costs nothing in quality.
What the extracted file inherits
Page content comes across exactly: text stays selectable, images keep their resolution, and each page keeps its own size and rotation. What does not come across is anything belonging to the document as a whole — bookmarks, the outline and document metadata are not carried into the new file. If a page referred to a bookmark elsewhere in the original, that reference is now pointing at nothing.
Splitting and reordering are different jobs
If the pages you want are the right pages in the wrong order, or a few of them are sideways, extraction is the wrong tool: it gives you the pages in their original order and orientation. Extract the range first, then reorder or rotate what came out. Doing it in that sequence keeps each step easy to check.
Frequently asked questions
Is my PDF uploaded to split it?
No. The file is read and the new document is written in your browser. This is worth caring about for the documents people usually split — contracts, bank statements, medical results — which are exactly the ones you would not want sitting on someone else's server.
How do I write the page range?
Individual pages separated by commas, ranges with a hyphen, and the two mixed freely: 1-3, 5, 8-10. Numbers outside the document are ignored rather than treated as an error, so a range that overshoots the end simply stops there.
Can I split a password-protected PDF?
Not while the password is on it. A document encrypted with an open password cannot be read at all without it, so remove the protection first in whichever application applied it.
Does splitting reduce quality?
No. The pages are copied, not re-rendered, so text stays text and images keep their original resolution. The file gets smaller only because it contains fewer pages, which is the one kind of size reduction that costs nothing.
