How to Split a PDF Online Free
Splitting a PDF means extracting a subset of its pages into a new, smaller document. Whether you need to send a single chapter from a large report, isolate an individual contract from a bundled document, or pull out just the pages relevant to a specific topic, NaughtyPDF's split tool lets you do it instantly — no software to install, no files uploaded to a server.
Understanding Page Range Syntax
The range field accepts a simple, comma-separated format:
- Single page:
5— extracts page 5 only. - Continuous range:
3-7— extracts pages 3, 4, 5, 6, and 7. - Mixed:
1-3, 5, 8-10— extracts pages 1–3, page 5, and pages 8–10, in that order. - Multiple outputs: Add another range row to produce a second PDF from a different set of pages.
Common Use Cases
- Sharing a single chapter: Extract pages 12–34 from a 200-page technical manual to share with a colleague.
- Removing cover pages: Start your range at page 2 to strip the cover from a document before emailing.
- Isolating exhibits: Pull specific exhibit pages from a legal bundle for filing.
- Submitting a single form: Extract the one-page form from a multi-page packet your institution sent you.
Frequently Asked Questions
Does splitting reduce quality?
No. The tool copies pages directly using pdf-lib — no re-rendering or re-encoding occurs. Text, images, and vector graphics are bit-for-bit identical to the original.
Can I create multiple output files?
Yes. Click "Add another range" to create a second (or third) output PDF from different page ranges of the same source file. All output files are ready to download individually.
Is there a page limit?
No server-side limit — everything runs locally in your browser. Very large PDFs (hundreds of MB) may take a moment on lower-powered devices but will complete successfully.
