How to split a PDF into separate files

By the Fusion Office team · Updated

Quick answer

To split a PDF, open Split PDF, choose your file and pick a method: page ranges (such as 1-3, 4-10), every N pages, or extract specific pages. Each part downloads as its own PDF. For size limits or chapters there are dedicated tools, covered below.

Split by page ranges or extract pages

  1. 1Open Split PDF and choose the file. The total page count is shown.
  2. 2Choose By ranges and type ranges separated by commas, for example 1-3, 4-10, 11-20. Each range becomes one file.
  3. 3Or choose Extract pages, type the pages you need (2, 5, 7-9), and decide whether they go into one PDF or one file each.
  4. 4Or choose Every N pages to cut the document into equal parts.
  5. 5Press Split PDF. Several files download together as a ZIP.

Split to fit an upload limit

When the problem is size rather than content, use Split by size. Enter the largest size allowed per file, like 5 MB, and you get as many parts as needed, in order. Try compressing the PDF first: you may end up with fewer parts.

Split at chapters or at a keyword

If the PDF has bookmarks (the outline in a PDF reader's sidebar), Split by bookmarks turns each chapter into its own file, named after the bookmark.

For batches like a month of invoices exported as one PDF, Split by text starts a new file on every page that contains a phrase you choose, such as “Invoice No.”. Scanned batches need OCR first so there is text to search.
