How to split a PDF without installing anything
Splitting a PDF is useful for a lot more than just "separating pages": you can keep only the chapter you need from a manual, pull a single page out of a contract to forward it, or break apart a scan that bundled several documents into one file. This tool does it right in your browser, with no software to install and no account to create.
There are three ways to work depending on what you need. Extract pages gives you a single PDF with exactly the pages you list, in the order you type them. Split into multiple PDFs turns each comma-separated group you enter into its own file, and hands you all of them together in a .zip. And split every page automatically creates one PDF per page in the document — handy when you need every sheet on its own.
Just like the merge tool, nothing loses quality here either: pages are copied from the original file as-is, with no recompression or conversion to images, so they keep their selectable text and original resolution.
Note: this tool can't open password-protected PDFs. If your file has one, remove it first with your regular PDF reader.
