Split PDF

To split a PDF, add it and choose a mode: page ranges you type (such as 1-3, 5, 8-12), every N pages, or one file per page. A summary shows exactly which pages go into each file before you split. Pages are copied rather than re-rendered, so quality is unchanged, and the file never leaves your browser.

How to use Split PDF

  1. 1Add the PDF you want to split.
  2. 2Choose a mode: split into ranges you type, split every N pages, or one file per page.
  3. 3Check the summary — it tells you exactly how many files you will get and which pages are in each.
  4. 4Press Split and download the results as a ZIP, or grab individual files.

How it works

The document is parsed once and its page tree is read. For each output file a fresh PDF is created and the requested pages are copied into it, keeping their original size, rotation and content.

Page ranges accept the notation you would type into a print dialog: 1-3 for a run of pages, 5 for a single page, and commas to separate them. Ranges outside the document are flagged before anything is generated.

The file is read into your browser's memory, changed there, and handed straight back to you. Nothing is uploaded, so there is no queue and no copy sitting on a server afterwards.

Worked example

Pulling the three chapters out of a 40-page report

  1. Add report.pdf.
  2. Choose "Custom ranges" and enter 1-12, 13-28, 29-40.
  3. Split and download the ZIP.

Result: Three PDFs of 12, 16 and 12 pages, named after the ranges they contain.

Tips and common mistakes

  • Page ranges count by position in the file, not by the number printed in the footer. Go by your reader's page counter, such as “7 of 40”.
  • For a stack of identical scanned forms, use “every N pages” instead of typing ranges — ten three-page forms split cleanly with N set to 3.
  • Read the summary before you press Split. It lists which pages go into each file, so a mistyped range is caught before anything is created.
  • When you send the parts to someone, keep the numbering in the file names — part 1 of 3, part 2 of 3 — so they know when they have them all.

Frequently asked questions

How do I write page ranges?
Use the same syntax as a print dialog: 1-5 for a range, 8 for a single page, and commas between them — for example 1-5, 8, 12-20. Spaces are ignored.
Can I get every page as a separate file?
Yes. Choose "One file per page" and each page becomes its own PDF, numbered in order, delivered together in a ZIP.
Do the split files keep the original quality?
Yes. Pages are copied rather than re-rendered, so nothing is re-compressed and text stays selectable.
Is the original file changed?
No. The file on your device is only read. The new documents are built separately and downloaded as new files.
Can I split a PDF by file size?
Not directly. Split by number of pages and check the sizes of the parts; if one is still too large, split that part again.
When should I use Extract PDF Pages instead?
When you want only a few pages and do not care about the rest. Splitting accounts for every page; extracting takes just the ones you name.
Can I split a scanned PDF?
Yes. Pages are copied whatever they contain, so a scanned page comes across exactly as it was.
