A practical guide to Split PDF
Split PDF divides a document by a strategy you choose: one file per page, every N pages, a set number of equal parts, a maximum output size, bookmarks, pages matching text, blank separator sheets, odd and even pages, or pages you pick by hand. Every strategy shows the resulting groups as thumbnails before anything is written, and the cut points can be corrected by hand.
Example: separate a scanner batch into its documents
Scan a tray of invoices with a blank sheet between each one, let the tool find the separators, check the detected pages, and export one named PDF per invoice.
Task-specific steps
- 1
Open the PDF and choose the strategy that matches the job, from one file per page to separating a scan on its blank pages.
- 2
Set the strategy's options, then let the tool inspect the document where it needs to read bookmarks, text, or page size.
- 3
Check the grouped preview, correct any cut point, and export the files or download them together as an archive.
Options that affect the result
- Eight strategies cover fixed sizes, equal parts, a byte limit, bookmarks, matching text, blank separators, odd and even pages, and hand-picked pages.
- The size strategy builds and weighs each part, so a limit set for an upload portal is measured rather than estimated.
- Output names come from a template with tokens for the original name, index, page range, bookmark title, and matched text.
- Files can be named from the text on their first page, using OCR when the scan has no text layer.
Limitations to know first
- Removing pages can break bookmarks or links that pointed to content outside the selection.
- Splitting a signed PDF creates new documents that do not retain the original signature validity.
- A single page larger than a chosen size limit cannot be made to fit, so that part stays over the limit and the tool says so.
Questions specific to this task
Can I split a PDF every 5 pages?
Yes. Choose the "Every N pages" strategy and enter 5. The preview shows the resulting groups before you export.
Can I split a scan into separate documents?
Yes. Put a blank sheet between each document before scanning, then choose the blank separator strategy. Detected separators are listed for you to confirm, and can be dropped from the output.
Can I split a PDF by file size?
Yes. Each part is built and weighed as it grows, so the limit reflects real output bytes rather than an estimate from the page count.
What is the difference between a range and specific pages?
A range includes every page between two endpoints. The hand-picked strategy lets you choose nonconsecutive pages such as 1, 4, and 9, either as one document or as separate files.
Can I keep selected pages together in one PDF?
Yes. Choose the hand-picked strategy and tick the option to combine the chosen pages into one document.
