Three ways to split a PDF
Open a PDF and choose what to do with it. Extract pages creates one new file containing only the pages you list, which is the quickest way to pull a single chapter, an invoice or a signed page out of a long document. Split into single pages creates one file for every page. Split every N pages cuts the document into equal chunks, for example every two pages for a stack of scanned two-page forms. The download links appear as soon as the files are ready.
Writing page ranges
Page numbers start at 1. Separate items with commas and use a hyphen for a range: 1-3, 5, 9-12 takes pages one to three, page five and pages nine to twelve. You can write end or leave the end of a range open, so 10-end and 10- both mean from page ten to the last page. Pages are kept in the order you type them, so 3, 1, 2 reorders the first three pages. If a number is out of range the tool says so instead of guessing.
Your file stays on your device
Splitting runs entirely in the browser with pdf-lib, an open-source PDF library served by this site. The document is read from your disk into memory and the new files are created there. Nothing is uploaded, which is why the tool is suitable for confidential paperwork such as tax forms, contracts and medical records.
What is preserved
Each page is copied exactly as it is, including text, fonts, images, page size and rotation, so text remains selectable and the quality does not change. Extracted pages often make a much smaller file than the original, but shared resources such as embedded fonts are included in every piece that needs them, so the pieces together can add up to more than the original size. Bookmarks and form logic that span the whole document are not carried over.
Related tasks
To remove pages, extract everything except the ones you do not want, for example 1-4, 6-end to drop page five. To combine pages from different files, extract them here and then join them with the merge PDF tool. To share a single page as a picture instead, use the PDF to image converter.
