Cut into parts, or pick pages
Cut into parts divides the whole file. Every page shows as a preview, and “Cut after” under a page starts a new part after it: a dashed line marks the cut and the next page is labelled with its part number. To cut the file into equal parts, enter how many pages each part should have under “Cut every few pages”: 2 turns a 9-page file into four 2-page parts and a last single page. Undo takes back the last change, and Clear cuts starts again.
Pick pages keeps only the pages you type. The pages you pick are highlighted and the rest fade, so you can check the numbers against the previews before you download. Choose One file to combine everything you typed into a single PDF, or A file per range to get a separate file for each comma-separated group.
How page ranges work
Type pages and ranges separated by commas: a single number like 7 for one page, or 10-12 for a run of pages. Mix as many as you need in one line, like 1-3, 7, 10-12, and they’re read left to right, in the order you wrote them: the tool doesn’t silently re-sort your list, so 5, 1-3 genuinely puts page 5 before pages 1 through 3 in the result.
Several parts come as one ZIP
Browsers often block a page from starting several downloads at once, so when a split makes more than one file, they’re packed into a single ZIP instead, built in this tab like everything else. Each file inside is named after the pages it holds, like report-p1-3.pdf, so they sort in page order.
What this tool doesn’t do
Splitting doesn’t compress the file, edit what’s on a page, or read text out of a scanned image. It doesn’t cut at bookmarks or by file size: you place the cuts yourself. To reorder or delete single pages, use Organize PDF; to combine several whole documents into one, use Merge PDF.
