Drop a PDF here
It stays on this machine. We never see your file.
Three ways, depending on what you actually need: cut at the ranges you type, chop it into equal chunks, or pick the pages you want and get one new file. The page grid shows which file each page lands in before you commit.
$99 once and the whole toolkit is yours — Acrobat is about $155 a year and stops working the day you stop paying. And the document stays on your laptop: we never see it, because nothing you open here is stored on a server.

How to write the ranges
Each comma-separated range becomes its own file. 1-3, 4-8 gives two files; 1-3, 9- gives the first three pages and everything from page nine to the end. last means the final page, and a range can overlap another if you want the same page in two files.
Downloads, one at a time
Splitting into many files gives you many downloads — PDFMod hands them to the browser one after another rather than zipping them on a server somewhere, so your browser may ask once whether to allow multiple downloads. Say yes; nothing has left the machine. A very large split is written in batches, because the parts can add up to far more than the file they came from: a report whose pages all share one heavy letterhead re-embeds that letterhead in every piece. If a run reaches the memory budget it stops, tells you which part it got to, and lets you carry on from there rather than taking the tab down with it.
What a split costs
Cutting a document up means copying pages into new ones, and the things a PDF keeps above its pages don’t come along: form fields stop being fillable, and bookmarks, accessibility tags, internal links and the document’s own title and author don’t survive into the pieces. That is true of every tool that splits a PDF; what is different here is that PDFMod measures your file before and after and names exactly which of those yours lost, rather than handing you a stack of downloads and calling it done.
