Three ways to split
Once your PDF is loaded you see a strip of page thumbnails and a list of parts. Each part is a range of pages, from one page number to another, and becomes its own PDF. You can build that list in three ways:
- Every N pages: type a number and press Apply every N. A 20-page file with N set to 5 becomes four parts of five pages.
- One PDF per page: each page becomes its own file. This works for documents of up to 10 pages.
- By hand: press Add part and fill in From and To for each range. Mix lengths freely, such as pages 1 to 2, then 3 to 9, then 10.
You can have up to 10 parts per run. They download together as a ZIP containing part-01.pdf, part-02.pdf and so on, in the order of your list.
Pulling out a single section
Click thumbnails to select them, then press Selection → 1 part. The part runs from the first selected page to the last, including everything in between. For pages that aren’t next to each other, such as 2, 7 and 15, add a separate part for each, or remove the pages you don’t want with Delete pages and keep the rest as one file.
Does splitting reduce quality?
No. Pages are copied into the new files exactly as they were, without re-rendering, so text stays selectable and images keep their original resolution. Each part is usually smaller than the original simply because it has fewer pages, though fonts shared across the document are repeated in each part.
To put parts back together, or combine them with other files, use Merge PDF.
Questions
Can the same page appear in two parts?
Yes. Ranges are independent and may overlap, so pages 1 to 6 and pages 5 to 10 both include pages 5 and 6. Handy when a table or section runs across the point where you want to cut.
My PDF won't open. It says it's encrypted.
Open it in your usual PDF reader with the password, save or print an unprotected copy, and split that. Mewix can’t remove passwords.
