Split PDF — Cut One PDF Into Separate Files Without Uploading

Mark boundaries in a drag-and-drop page grid and export as separate PDF files.

PDF Split works by marking, not by choosing a page count: you scissor-mark the last page of each chunk you want, and every marked run in the grid becomes its own downloaded PDF. There's no fixed split interval and no separate upload step for each piece — one drop, one grid, as many output files as boundaries you draw.

How to split a PDF

Load the PDF you want to break up; each page shows as a numbered thumbnail.
If the pages are out of sequence, drag them or use Earlier and Later to fix the order first.
Click the scissors icon on the last page of every part you want; the note under the grid shows how many files you will get and how many pages each holds.
Click Export, then download each part from its own button — the files are named after the original with -part1, -part2 and so on.

What a split boundary actually means

Marking a page toggles a split-after-this-page flag rather than a page number, so the boundary travels with that specific page if you later drag it somewhere else in the grid. Walking the ordered page list and starting a fresh output file every time that flag appears is the entire splitting logic — there's no separate concept of a fixed chunk size anywhere underneath it.

Marking the very last page in the grid is a harmless no-op: there's nothing after it to start a new file with, so that boundary is simply ignored rather than producing an empty trailing document.

Splitting after reordering, not just extracting

Because Split shares its page grid with Merge, you aren't limited to slicing one file into pieces in its original order — you can drag pages around, or even drop in a second PDF and interleave its pages, before drawing your split boundaries. A split output can therefore contain pages that never sat next to each other in the source document.

Splitting is lossless

Each part is assembled by copying the original page objects into a new PDF, so fonts, images, vector drawings and any rotation you applied come through unchanged. No page is rasterized or recompressed, and the whole job runs inside your browser tab, so the document is never uploaded while it is being cut up.

Naming and rotating the pieces

Marking zero boundaries exports a single file with an edited suffix; marking one or more boundaries switches every output to a part-one, part-two naming pattern instead, numbered in the order the boundaries appear in the grid. Rotation set on any individual page travels with it into whichever segment it ends up in, independent of where the boundary lines fall.

Each part appears as its own download button rather than inside a ZIP archive, so you can save only the pieces you need.

Split limits: any number of parts, 300 pages per free document

Splitting a single loaded document into any number of pieces isn't treated as a batch the way loading many separate files for a merge is, so it isn't affected by this app's free-tier document-count limit.
On the free tier the source document can be up to 300 pages long, checked when you click Export; Pro accepts longer files. Very long documents stay usable because only the rows near your current scroll position are kept on screen.
The tool never infers where a natural split point — a chapter start, a blank separator page — belongs; every boundary is one you draw yourself, so a document with a hundred implicit sections needs a hundred manual marks if you want each one as its own file.

Questions people ask about PDF Split

How do I mark where a PDF should split?: Click the scissors icon on a page in the grid to mark it as a boundary; every page up to and including a marked one becomes the end of one output file, and the next page starts the following one, with no limit on how many boundaries you draw.
How do I split a PDF into single pages?: Click the scissors on every page except the last one, then export; each page becomes its own file. There is no one-click split-all button, so for a long document that means one click per page before you export.
Can I split a PDF every few pages automatically?: No. There are no page-range or every-N-pages modes here; boundaries are placed only by hand with the scissors icon. For a regular pattern, such as every third page, click the scissors on pages 3, 6, 9 and onward.
How do I extract just one page from a PDF?: Either delete every other page with the trash icons and export, or mark scissors on the page before it and on the page itself, export, and download only the part that holds that single page. Both give you a one-page PDF.
Does splitting a PDF reduce quality?: No. The pieces carry the same page content as the source, copied rather than redrawn, so text stays selectable, scans keep their resolution and nothing is recompressed. Only the grouping of pages into files changes.
Does splitting auto-detect chapters or sections?: No. There's no content analysis behind this tool at all — it only responds to the boundaries you mark by hand, so if a document has ten natural chapters you'd mark nine boundaries yourself to get ten output files.
What happens if I mark the boundary on the last page?: Nothing — marking the final page in the grid has no effect, since a boundary only matters as the point where the current output file ends and the next one begins, and there's no page left afterward to start one with.
Is there a limit on how many pieces I can split a PDF into?: No — each marked boundary becomes one more output file with no ceiling on the total, and because splitting one document isn't treated as a multi-file batch, this app's free-tier document-count limit doesn't apply to it either.
