Split a PDF into several files
Cut one PDF into separate files: one per page, by page ranges, every N pages, or one file per chapter using the bookmarks.

When you'd use it
- Your scanner put a whole stack of separate letters into one long PDF.
- A 300-page manual is too big to email, so you need it in chapter-sized pieces.
- Your payslips for the year arrived as one file and each month needs its own PDF.
Just say what you need
There are no menus to learn. Drop your file on pdfagents.ai and type it the way you would say it:
- “split into separate pages”
- “split 1-3, 4-6, 7-”
- “split by chapter”
How it works
- Drop the PDF.
- Choose how to split, or type the ranges.
- Download a ZIP with the parts.
A trailing dash (7-) means “to the last page”.
Questions
- How does splitting by chapter work?
- It uses the PDF's top-level bookmarks and needs at least two that point to different pages. Pages before the first bookmark become a “front” file, and each part is named after its chapter.
- What happens to pages I don't include in any range?
- They are left out. Each range you type becomes its own file. Ranges may overlap, so the same page can end up in two files.
- With “every N pages”, what if the page count doesn't divide evenly?
- The last file gets whatever is left: a 7-page PDF split every 3 pages gives files of 3, 3 and 1 pages.
