Split PDF
Break a PDF into separate files. Runs entirely on your device.
Runs on your device. The file is never uploaded.
Split PDF cuts a document into fixed-length runs of pages, one output file per run, named with your file's stem and a three-digit counter: report-001.pdf, report-002.pdf. Pages per output file defaults to 1, giving one PDF per page. Anything but a whole number of 1 or more is refused before a page is copied.
Questions
How does the split decide where to cut?
By a fixed number of pages. "Pages per output file" of 1 gives you one PDF per page; 10 gives you a file for pages 1 to 10, another for 11 to 20, and a shorter last file with whatever remains.
What are the output files called?
Your file's name with a three-digit counter: report.pdf becomes report-001.pdf, report-002.pdf and so on, in page order, so they sort correctly in any file manager.
Can I split at specific places instead of every N pages?
Use Split PDF by size, bookmark or text for that, it cuts where a size limit is reached, where a top-level bookmark starts, or before a page containing text you name. To pull out one particular range instead, use Extract PDF pages.
Do I get a ZIP or separate files?
Separate PDFs, listed on the page with a download for each. Nothing is zipped, so you can take only the parts you want.
Does splitting lose quality?
No. Each output is built by copying the original pages, so text stays text and images keep their original data. The parts together are usually a little larger than the original, since each file repeats the resources its pages need.
