Free Online PDF Splitter
SmarterSources's Split PDF tool makes it easy to break a large PDF into smaller, more manageable files in seconds. Whether you need to send a single chapter from a textbook, share specific sections of a contract, or simply reduce file size for email, this tool handles it all directly in your browser with no uploads and no sign-ups required.
Three Flexible Ways to Split
Choose the split method that fits your workflow. "Split All Pages" creates a separate PDF for every page in your document, perfect for breaking apart scanned documents or extracting every slide from a presentation. "Split by Range" lets you define exactly which pages go into each new file using simple page ranges like "1-3, 4-6, 7-10." "Split Every N Pages" automatically divides your document into equal chunks of two, five, or however many pages you choose.
Visual Page Previews
Before you split, the tool renders every page of your PDF as a thumbnail so you can see exactly what you're working with. In range mode, each group is color-coded so you can instantly confirm which pages will end up in which output file. No guessing, no mistakes.
Your Documents Stay Private
Every step of the splitting process happens locally in your browser. Your PDF is never uploaded to any server. The output files are generated on your device and downloaded directly. This makes SmarterSources the most private PDF splitter available online, ideal for sensitive documents like financial records, legal contracts, or personal files.
Frequently Asked Questions
How do I split a PDF into individual pages?
Upload your PDF, select "Split All Pages" mode, and click "Split PDF." The tool will create a separate PDF for every single page in your document. You can then download each one individually or use the "Download All" button to save them all at once.
Can I split a PDF into custom page ranges?
Yes. Select "Split by Range" mode and enter your desired ranges separated by commas. For example, entering "1-3, 4-6, 7-10" will produce three PDFs: one with pages 1 through 3, one with pages 4 through 6, and one with pages 7 through 10. The page grid will color-code each group so you can verify before splitting.
Is there a file size or page limit?
There is no artificial limit. Since all processing runs in your browser, the only constraint is your device's available memory. Most modern devices can comfortably handle PDFs with hundreds of pages without any issues.
Are my PDF files uploaded to a server?
No. This tool is 100% client-side. Your PDF is processed entirely within your browser and never leaves your device. The split files are generated locally and downloaded directly to your computer, ensuring complete privacy.
What happens to the quality of my PDF after splitting?
The split files are exact copies of the original pages. There is no re-compression, quality loss, or modification of any kind. Text, images, fonts, and formatting are all preserved exactly as they appear in the original document.
Can I split a password-protected PDF?
This tool works with standard, unprotected PDFs. If your PDF is password-protected, you'll need to remove the password first using a PDF password removal tool, then upload the unprotected version for splitting.
