About Split PDF
Split PDF cuts one PDF into several smaller files. You decide where the cuts go: by page ranges you type, by a fixed number of pages per file, or one file for every page.
Splitting helps when a scanner produced one long file for a stack of separate documents, when a portal only accepts uploads under a certain size, or when you need to send chapter three to one person and the appendix to another. Teachers split a workbook into weekly handouts. Accountants split a year of statements into months.
The tool copies pages without changing them. Each new file keeps the text, images and page size of the original.
How to use Split PDF
- Choose the PDF you want to split or drop it onto the page.
- Pick a mode: By ranges, Every N pages, or Every page.
- For ranges, type groups separated by commas, such as 1-3, 4-7, 8-. Each group becomes one file.
- Check the preview. Every thumbnail shows which output file the page lands in.
- Click Split PDF and download the files as a ZIP, or one by one from the list.
Three split modes
Custom ranges, fixed-size chunks or single pages. The preview shows the result before you commit.
Live page map
Each thumbnail labels its target file, so you catch a wrong range before you download.
ZIP download
Get every part in one ZIP, or download individual files from the list.
Private by default
Splitting happens on your device. The original never leaves your computer or phone.
How page ranges work
The range box follows the syntax most print dialogs use. A single number such as 5 means page 5. A hyphen marks a range, so 2-6 means pages 2 through 6. Leaving out the end, as in 9-, means page 9 to the last page. Leaving out the start, as in -3, means pages 1 to 3.
Commas separate output files. Typing 1-3, 4-6 gives you two files with three pages each. You can repeat pages across groups: 1, 1-5 creates a file with only the cover and a second file with the cover plus the next four pages. Groups can also come in any order, and the files follow the order you type.
Every N pages works well for documents with a fixed structure, such as a batch of two-page forms scanned in one go. Set N to 2 and you get one file per form. Every page is the extreme case and gives you one PDF per page, handy for sending single certificates or invoices.
Each output file is a full, independent PDF. The tool copies only the resources each part needs, so splitting a 40 MB scan into ten parts gives you files of roughly 4 MB each instead of ten copies of the whole thing.
Tips for better results
- Use Extract PDF Pages when you want one file with a selection of pages instead of several files.
- If a portal limits upload size, split by Every N pages and raise N until each part fits.
- Rotate sideways pages first with Rotate PDF, then split. The rotation carries into every part.
- Rename the parts after downloading. The tool names them after the original file plus the page range.
Questions and answers
Does splitting reduce quality?
No. Pages get copied without re-encoding, so text and images look the same as in the original.
Can I split a password-protected PDF?
Remove the password first with Unlock PDF. The split tool can't read encrypted pages.
What is the maximum file size?
There is no fixed limit. Your device's memory decides how large a file it can handle.
Why are my split files almost as large as the original?
Some PDFs share one large resource, such as an embedded font or background image, across all pages. Each part needs its own copy of that resource. Run Compress PDF on the parts if size matters.
Can I split a PDF on my phone?
Yes. The tool works in mobile Chrome and Safari. Downloads go to your phone's Files or Downloads folder.
