How to Split a PDF: Extract Pages from Any PDF Document
Key Points
- Split extracts selected pages into separate PDF files without altering the original
- Useful for sharing specific sections without sending the entire document
- Processing happens entirely in your browser—your documents stay private
Sometimes you only need a few pages from a large PDF—a single chapter from a textbook, one form from a packet, or specific pages from a report. Splitting PDFs lets you extract exactly what you need, making files smaller and easier to share.

Common Use Cases
Extract a Chapter or Section
Pull out a single chapter from a textbook or manual for focused reading or printing without wasting paper on the entire document.
Share Specific Pages
Send only the relevant pages of a contract or report to a colleague instead of the full 100-page document.
Reduce Email Attachment Size
Extract only the necessary pages to keep the file under email attachment limits (typically 25 MB for most providers).
Organize Scanned Documents
When a scanner produces one large PDF from a batch scan, split it into individual documents for proper filing and naming.
Split Tips
Preview page thumbnails before splitting to confirm you're extracting the correct pages.
Use page range selection (e.g., 1-5, 8, 12-15) for efficient extraction of non-consecutive pages.
After splitting, rename each extracted file descriptively so you can find them later.
Keep the original PDF as a backup—splitting creates new files and doesn't modify the source.
All PDF splitting is performed locally in your browser. No documents are uploaded to external servers, ensuring your sensitive information remains private.
