Complete Guide to Splitting PDF Files
What this tool does
PDF splitting divides a multi-page PDF document into smaller, separate files. Pull specific chapters from a long report, separate signature pages from a contract, break a large manual into per-chapter files, or extract particular pages from a scan. Splitting happens locally in your browser using pdf-lib — your file is never uploaded to any external server, which matters most for legal documents, financial reports, or personal records containing sensitive information.

- Enter all ranges at onceEasier than running the tool multiple times.
- Double-check your page numbersPDF and printed page numbers often differ when the document has a cover page.
- Remove pages by keeping the restSplit into the sections you want to keep, then recombine with the Merge PDF tool.
- Verify legal documents one by oneConfirm the page content of every output file is correct.
- Note your recurring rangesRepeat jobs like monthly reports can reuse the same specification.

FAQ
Split PDF FAQ
These answers explain what the tool does, what files it supports, and where the current limits are.
Does this work with password-protected PDFs?
No. The current version requires unprotected PDF files.
Can I extract non-consecutive pages?
Yes. Enter ranges like "1-3, 5, 8-10" to extract exactly the pages you need.
Is there a page limit?
The browser handles most PDFs well. Very large files (500+ pages) may take longer.
Can I split a PDF into equal-sized chunks?
Yes. Enter evenly spaced page ranges like "1-10, 11-20, 21-30" to split a document into equal chunks. The tool supports any combination of ranges and individual page numbers.
Does splitting preserve bookmarks?
Bookmarks from the original PDF are not carried over to the split output files. The split pages retain all visual content, text, and images but document-level metadata like bookmarks may be lost.
