How to split a PDF
Split one PDF into several smaller files. The live preview colors each page by the file it will go into, so the result is visible before you split.
Add your PDF
Drag the PDF onto the upload box, click to choose it, or import it from Google Drive. A password-protected file opens after you enter its password.
Choose a split mode
Next to Split mode, choose Pick split points, Every N pages, After pages, Page ranges, Every page or Odd / even. Modes that need a number show an input for it, such as Pages per file.
Check the live preview
In Pick split points mode, click a page or the gap after it to start a new file after that page. Shift-click marks a run of pages. In the other modes, clicking between pages adjusts the split points by hand. The preview lists every file that will be created.
Split and download
Click the split button in the header. Its label shows how many files will be created. Several files are downloaded together as a ZIP. The results screen lets you preview each file, download, save to Google Drive, open a file in another tool, or delete the files.
Split by page ranges
In Page ranges mode, type ranges such as 1-3, 5, 8-last. Each range becomes its own file. Tick Merge into one PDF to get a single file with only those pages. Pages not covered by any range are listed, with an Add them too button.
Bookmarks and file names
Open More options to set these. Bookmarks that point to pages in a file are kept in that file; tick Discard bookmarks to remove them. Output file names takes a pattern such as [BASENAME]-[CURRENTPAGE]. Undo and redo (Ctrl+Z and Ctrl+Y) step through your changes.
Page range rules and what each split file keeps
How the Page ranges box reads what you type
- Separate entries with commas, semicolons or spaces. 1-3, 5 and 1-3 5 mean the same thing.
- "last" and "end" both stand for the final page, so 10-last and 10-end give the same file.
- Either side of a range can be left open: -4 means pages 1 to 4, and 12- means page 12 to the end.
- A range has to run forwards. 9-5 is rejected with a message rather than flipped, and so is any number higher than the page count.
- The same page can appear in two ranges. 1-5, 5-10 puts page 5 in both files, which helps when a new section starts halfway down a page.
"After pages" is stricter. It only takes single page numbers, and it won't accept the last page, because there's nothing after it to put in a new file.
Merge into one PDF keeps your order
With "Merge into one PDF" ticked, the pages go in the order you typed them. They aren't sorted. 10-12, 1-3 gives a six-page file that starts with page 10, and 1, 1, 1 gives three copies of page 1. That makes the box a quick way to pull out a handful of pages and reorder them in one step. For anything fiddlier, Organize pages lets you drag thumbnails around instead.
Getting file names that sort properly
With "Output file names" left empty, the parts get descriptive names such as report-pages-1-3.pdf or report-page-7.pdf. A pattern gives you more control, and a few variations are easy to miss:
- [FILENUMBER###] pads the number to three digits: 001, 002, 003. Without padding, many file lists put file-10 before file-2.
- [FILENUMBER+100] starts counting at 101, which is useful when this batch continues an earlier one.
- [CURRENTPAGE] is the first page of each part, and takes the same # padding.
- [TIMESTAMP] adds the date and time of the split, like 20261004_143015.
If two parts would end up with the same name, the later one gets " (2)" added, so nothing inside the ZIP overwrites anything else. Characters that Windows or macOS won't allow in a file name, such as a colon or a question mark, are replaced with spaces.
What goes into each new file
Every part is built as a fresh PDF that contains only its own pages. Page content, page size, rotation and annotations such as comments and highlights travel with each page, and shared fonts and images are stored once per part.
Bookmarks are copied only when they point at a page inside that part. If a chapter bookmark points outside the part but some of its sub-bookmarks point inside, those sub-bookmarks move up a level instead of disappearing.
Things that belong to the whole document rather than to a page don't come along:
- The title, author and subject in the document properties. Edit metadata can set them again on the parts that need them.
- The password. Parts of a protected PDF are saved without one, so run Protect PDF on any part that's going somewhere sensitive.
- The form setup. Don't count on fillable fields still working in the parts. Fill them in and run Flatten PDF on the original first.
