How to split a PDF with PDFTheory
Use the free Split PDF tool to divide your document in seconds.
- Go to the Split PDF tool.
- Upload the PDF you want to split — drag and drop it, or click to browse your files.
- Choose how you'd like to split: by page range, into equal parts, or one page per file.
- Click Split.
- Download your split files individually or as a ZIP archive.
That's it — your original file stays untouched, and you get exactly the pages you need.
Extract specific pages instead
Sometimes you don't need to split a file into multiple parts. You just want a few specific pages pulled out. The Extract Pages tool is perfect for this.
Upload your PDF, select the pages you want (even non-consecutive ones like pages 2, 7, and 15), and download a clean new file with only those pages.
This is especially handy when you're preparing documents for a meeting, pulling receipts from a financial report, or isolating a single form from a packet.
Real-world ways people use PDF splitting
Students: Focus on what matters
Instead of scrolling through an entire textbook PDF, split out the chapters you're studying this week. It makes note-taking easier and keeps your files lightweight.
Professionals: Share only what's relevant
Need to send a contract section to a client for review? Split the document so they see only the relevant clauses — no more, no less. It keeps things clean and confidential.
Small business owners: Stay organized
Break long invoices, catalogs, or manuals into separate files by month, department, or product line. Easier to file, easier to find later.
Tips for better results
Clean up first
Before splitting, consider removing any blank pages from your document. This ensures your split files don't contain unnecessary empty pages.
Add page numbers after splitting
Once you've split a document, the original page numbers may not match up anymore. Use the Page Numbers tool to add fresh numbering to each file.
Recombine if needed
