Split PDF

Comma-separated single pages and hyphenated intervals, so `1-4, 7, 10-15` works as you would expect. A range can be open at one end: `5-` runs from page 5 to the end, and `-3` is pages 1 to 3. Ordinary hyphens, en and em dashes, spaces and semicolons are all accepted, and a reversed range such as `5-2` is read as 2-5. With Split Parts, each range you type becomes its own file, in the order you typed it. Anything that cannot be used is listed underneath the box as you type: a page number past the end of the document, a token with two dashes, or text that is not a number. A range that only partly overruns the document is clamped and tells you what it read instead.

Choose the naming template: Part Index gives `Book_part1.pdf`, `Book_part2.pdf`; Page Range gives `Book_pages_1-10.pdf` using the page numbers from the original document, not the grid positions; and Custom lets you set your own prefix. Each part is named after the file its pages actually came from, which matters once you have added a second PDF to the queue.

Yes. Pages are copied whole, with their fonts and vector artwork intact, so print quality is identical to the original. The one exception is Max Size mode. A part over the limit is first re-saved more compactly, then cut into smaller files by page. Only a single page that is still over the limit, or an output that may not be cut, such as one merged PDF or one PDF per page, is re-rendered as images, and only when that makes it smaller. That does lose vector sharpness. A file can still end up over the limit, and the result says so. Every other mode is a straight copy.

Each output is a new document containing the pages you chose, so anything stored at document level rather than on a page does not come with it: bookmarks, the document metadata and attachments. Form fields on the pages you chose are the exception: they come with their pages and stay fillable, with any values already entered. The grid shows a bookmark badge on pages that are outline targets, which is there to help you find chapter starts, not a promise that the outline survives.

It depends on the protection. Split PDF has no password box, so a file that needs a password to open is refused, with advice to remove the password with Unlock PDF first. A file that opens but carries restrictions, such as no printing or copying, splits normally, and the parts do not carry those restrictions.
